INTERNATIONAL ACCELERATOR RADIOLOGICAL PROTECTION E-MAIL (IARPE) NEWSLETTER "The Official Publication of the Accelerator Section of the Health Physics Society" (with Contributions from International Correspondents) ====================================================================== April/May 1994 Vol. #3, #2 ====================================================================== OFFICERS ====================================================================== President: Geoff Stapleton, CEBAF Past President: Ralph Thomas, LLNL President Elect: Nisy Ipe, SLAC Secretary: Bob May, CEBAF Treasurer (designate): Joe McDonald, PNL Directors (1 year): Paula Trinoskey, LLNL Gerry Fallon, MIT BATES Directors (2 year): Jerry Miller, LAMPF Carter Ficklen, CEBAF Directors (3 year): Steve Musolino, BNL De Vaughn Nelson >From the Editor Lutz Moritz ====================================================================== A discussion at the meeting of the Accelerator Section held in Arlington Texas during the 8th International Conference on Radiation Shielding raised the issue of whether we should try to push for a session devoted to Accelerator Radiological Protection at the 1996 IRPA congress to be held in Vienna. This was felt to be possible only if the Accelerator Section could claim to represent the international accelerator radiation protection community. There were a significant number of the international participants of the ICRS8 and the associated OECD/NEA workshop present at the section meeting but it appeared that some felt that it was a question of whether sufficient papers would be presented to make up a special session. We would therefore like to poll the Accelerator Section members and Newsletter subscribers to see how many intend to make a presentation related to accelerator radiation protection at the 1996 IRPA congress. Please send an E-mail message to Nisy Ipe at with the title of your intended paper with a copy to Manfred Hoefert at who is coordinating the European effort. Time is of the essence as the planning for the IRPA congress is well advanced, so let us know of your intentions as quickly as possible. Several members at the meeting indicated that they would like a copy of the list of subscribers and their e-mail addresses. I have therefore appended the latest list to this Newsletter. It is always possible to obtain an updated list by sending an e-mail message to . The e-mail message must contain the command: "REView IARPE-L" (no quotation marks) and may be followed by options: "BY sort_field" (again no quotation marks) where 'sort_field' may be any of the following: Country, Name, NODEid or Userid. SECTION BUSINESS ====================================================================== Minutes of the Section Meeting Held at Arlington Texas, (April 28, 1994) Board Members Present: Nisy Ipe, Lutz Moritz, Geoff Stapleton (chair) and Ralph Thomas. Apologies for absence: Apologies were received from Jerry Miller, Joe McDonald, Steve Musolino, Carter Ficklen, and Bob May. The main purpose of the meeting was to review the final arrangements for the various accelerator section functions to be held at the annual HPS meeting at San Francisco. It was also intended to make a presentation to the many overseas visitors attending the two conferences being held during the current week at Arlington. Minutes of the ad hoc meeting held at Albany, NY were made available to those present, the chairman expressed gratitude for the useful business conducted at Albany by Bob May who acted as Chairman for the meeting. 1. San Francisco HPS meeting June 26-30 1994 (a) Technical Program Nisy Ipe informed the meeting that she was pleased with the material to be presented at the SF technical session and that there was no change to the program published in the Feb./March IARPE. (b) Accelerator Section Night-out The arrangements for the event were well in hand and needed very little discussion. The chairman congratulated the organizers of the event which should prove to be most enjoyable. Rick Donahue agreed to provide a program for the actual events. 2. Finances The Treasurer provided a statement of income and expenditure and an account balance for the four months ended December 31, 1993. The Treasurer reported that he was still having difficulty in obtaining up-to-date statements and a current list of paid up members from the HP. He would try to find out whether other sections of the society were experiencing similar difficulties. 3. Documentation Ralph Thomas reported on his and Wade Patterson's work in producing a history of accelerator radiation protection. It was fully expected that this volume would be ready by the time of the HPS meeting at San Francisco. Ralph also reported on his work in compiling a biblio- graphy of work in the field of accelerator radiation safety. He informed the meeting that his intention was to provide a substantial work which would contain considerable discussion and analysis as well as an extensive bibliography, however, he felt that it would be necessary to obtain the financial support of a sponsor because of the scale of the work involved. 4. Scientific and Technical Matters The only topic discussed was the response of the technical panel to a proposal made by Wade Patterson to petition, through a letter from the Section, ICRP/NCRP to establish and publish conversion factors that would allow the determination of absorbed dose (in Grays) and dose equivalent (in Sieverts) from measured values of the external, ambient fluence (in particles/cm2) of neutrons and gamma rays. Suggested forms would be either tables, graphs or analytic functions which would be official ICRP and NCRP numbers. Ken Kase (chairman of the scientific and technical group) had considered this proposal and his written response was made available to Board members present. His main recommendation was to delay taking action on this proposal until after the ICRP-51 committee had reported its work. This was expected this Summer. Ralph Thomas who is chairman of that ICRP-51 committee spoke and gave the members present an understanding that all the quantities requested in Wade's draft letter would be able to be calculated from the information included in ICRP-51. It was agreed to await the ICRP-51 report before taking any further action on this matter. 5. Amendments to Section Charter Carter Ficklen (section parliamentarian) provided a written summary of the situation with regard to proposed changes in the Section Charter. Although the required changes had not been finalized he did not expect any problems or hindrances to arise in making the changes. He further informed the meeting that the section should be putting in hand written bylaws and agreed to lead this effort if he could enlist the help of a small committee. The meeting agreed to Carter's proposal and requested that he should proceed with recruiting some help. 6. Newsletter The chairman congratulated the Newsletter editor (Lutz Moritz) on the very interesting features and articles that appeared in the Newsletter. The Newsletter was considered a most important part of the sections activity. 7. Nominations The chairman informed to meeting that nominations were required for two Directors and a Secretary; also that the Treasurer and Newsletter Editor would agree to serve a further term. He requested that any nominations should be sent to Jerry Miller [(505) 665 4492] who was leading the nominations committees effort. 8. International Collaborations Nisy Ipe spoke about the possibilities for collaborative efforts between various institutions world wide. She stressed the fact that even though the Health Physics Society is "American", many efforts have been made to make the Accelerator Section truly international. The Accelerator Community is a small community and there is no other organization besides the Section which can foster collaborative efforts worldwide. She stated that the section would be willing to accept 5 year memberships from the overseas colleagues (a recommendation made earlier by Graham Stevenson, CERN and Shunichi Tanaka, Japan). She also indicated that the HPS journal accepts papers from around the world, and recently there has been a surge in submission of papers related to accelerators. In order to meet this need, the HPS editor is appointing a new associate editor (from overseas) with expertise in the accelerator field. Nisy proposed the following collaborative efforts: o A Session on Accelerators at IRPA o An International Workshop/ Conference o Exchange Programs between Various Labs/Organizations (After the meeting, 7 international colleagues joined the section.) 9. Any Other Business (A report was submitted to the chairman by Steve Musolino but was not presented to the meeting (the chairman's E-mail system was giving problems) but is included here in the minutes for information. (a) A letter of invitation was sent to all HPS members who have indicated an accelerator specialty but who have not yet joined the section. We need input from the HPS to see how successful that effort was. (b) A brief article was put in the HPS Nov 1993 newsletter requesting members who have not provided an E-mail address to do so. (c) All affiliates of IRPA have been sent a letter and application form requesting they publicize the accelerator section among their members. There being no other business, the chairman thanked those attended and adjourned the meeting. NEWS FROM IARPENL CORRESPONDENTS ====================================================================== News from FNAL Dave Boehnlein ---------------------------------------------------------------------- The big news at Fermilab is that the CDF collaboration has found direct evidence of the existence of the top quark. Although the data are not sufficient to definitely state that the top quark has been discovered, the results of this analysis are the most significant to date in the search for the elusive (every article I've read in the papers uses that adjective; I'm not going to buck the trend) top quark. The data used in this analysis are from collider run 1a, which took place last year. Collider run 1b is currently in progress and we hope to extend collider operations for another 12 to 18 months in order to collect sufficient data to make a definite pronouncement on the top. For those readers whose background is not in high energy physics and are wondering what all the fuss is about, the discovery of the top quark would represent confirmation of an important component of the Standard Model, the currently accepted model of the fundamental workings of the subatomic world. In this model, all things are made of quarks and leptons, which interact through four forces: the strong nuclear force (which holds nuclei together), the weak nuclear force (responsible for beta decay), the electromagnetic force (which holds atoms together) and gravity (unimportant in subatomic physics but keeps lab equipment on the floor). The leptons include electrons, muons, a more exotic but similar and heavier beast called the Tau lepton, and their associated neutrinos. Leptons do not "feel" the strong nuclear force (hence the relatively long range of energetic electrons and muons in matter). They interact via the electromagnetic force and the weak nuclear force. The quarks do feel the strong nuclear force and are considered to comprise all strongly-interacting particles. These include baryons (three-quark states) and mesons (quark-antiquark states). The quarks come in different flavors (nobody has actually tasted one; "flavor" is the name given to the quantum mechanical degree of freedom which varies among quarks of different mass); there are five known flavors: up and down, strange and charm, bottom. Theory predicts that quark flavors come in pairs and this is observed with the first four. The missing flavor is top. Where do we see quarks? The up and down quarks make up garden variety protons (uud) and neutrons (udd) as well as the common pi mesons (u ubar, d dbar, u dbar). The heavier quarks make up heavier, unstable, and therefore more exotic particles, e.g., the strange quark is found in the Lambda baryon (uds, basically a strange neutron) and the K mesons (s ubar, s dbar). The flavor quantum number determines some properties of these particles since it is a conserved quantity in strong interactions. Since quarks are never observed alone, the object sought in the collider experiments is actually a t tbar meson, which may decay through one of several channels. The CDF group presented a preliminary cross section calculation of 14 picobarns for production of this meson in all decay channels and a preliminary mass estimate of 174 GeV/c**2. It is hoped that an understanding of the very large mass of this object (the next heaviest, the bottom quark, is about 5 GeV/c**2) will provide insight into the nature of matter and how mass comes to exist. A cautionary note comes from D0, the other collider experiment at Fermilab. They do not see evidence of the top quark in their data. The events observed at D0 are consistent with the expected background. However, if the cross section calculated by CDF is correct, they should be seeing some events above background. As stated by both experiments, more data are needed to reduce the possible impact of statistical fluctuations before a definite statement on the top quark can be made. And now for something completely different... A conceptual design study has been authorized for the proposed 400 MeV experimental beamline at Fermilab. A committee is studying the possible beamline parameters, beam dump siting, shielding requirements, construction of an experimental area and a number of miscellaneous related matters. The plans under consideration call for the beamline to be able to deliver not only protons, but H- and H0 ions as well. In addition to interest from the health physics community, there has been interest on the part of the atomic physics, medical physics and industrial sectors. The study is to be completed by June. DJB NEWS FROM SLAC (Vashek Vylet ) ====================================================================== RECENT RADIATION PHYSICS ACTIVITIES FOR THE B-FACTORY B-factory, a new project that will take SLAC into year 2000, is getting launched at SLAC. The project is also called PEP-II because it will utilize the existing PEP tunnel to house the two accelerator storage rings; a positron ring (4 GeV, called LER) atop an electron ring (10 GeV, called HER). Each ring has a circulating current of 3 A, corresponding 1.4E14 stored beam particles. Major RP activities for PEP-II during the initial phase were the estimation of the synchrotron radiation dose to the magnetic coil insulation and also the dose to any electronic equipment to be placed inside the tunnel. The possibility of placing the electronic equipment in the tunnel would result in a substantial cost saving. EGS4 was used to estimate the synchrotron radiation dose and an analytical code was used to estimate the dose from high energy photon and neutron dose resulting from various beam loss scenarios. The results show that the dose to the magnet insulation is acceptable and there is one location (between HER and the floor) that is suitable for the electronic equipment. RP notes are being written documenting the study in progress. (James Liu, ) NEW EXPERIMENT IN FFTB (FINAL FOCUS TEST BEAM) The operation of linac at SLAC resumed in March delivering beams to FFTB and SLC. The allowed repetition rate for the FFTB has been increased to 30 Hz. Previously the beam line had been run at 10 Hz. Radiation measurements were performed and the existing FFTB shielding and radiation safety systems were found to be adequate. The increase in beam power was therefore allowed without further modifications. The objectives for this set of runs are to commission two beam size monitors from KEK and ORSAY as well as detectors for E-144 experiment. E-144 is designed to investigate the interaction of electrons with an intense electric field (in excess of 1.2E16 V/cm=QED critical field). This is achieved by exploiting the high energy of the FFTB beam (46.6 GeV) and compressing a 1 Joule laser pulse into a pico-second time interval. The back-scattered gamma as well as e+e- pair are measured in position sensitive Si-Pb and Si-W calorimeter. The main radiation safety concern for this experiment is generation of muons created by backscattered photons impinging on the forward angle calorimeter. The muon flux was estimated with a combination of the EGS4 code, to estimate the photon track length distribution in the calorimeter, and a Monte Carlo muon transport code. Measurements were conducted showing that the muon dose was within the range of estimated values. After the initial beam check-out of detectors, another set of runs are planned for September 1994.
