The Past President's Message

Mike  Grissom

Now that the 2011-2012 Accelerator Section Board year is winding down, I hope to see you this coming July at the 57th HPS Annual Meeting in Sacramento, California. As reported in the Preliminary Program, the Accelerator Session will be from 8:15 AM to Noon on Tuesday, July 24, 2012 in Room 306 at the Sacramento Convention Center. Immediately following the Accelerator Session, we will have the HPS Accelerator Section’s Annual Business Meeting also in Room 306. At that time, the 2012-2013 Section elections will be completed, final votes counted, and results announced. I would like to thank Steve Frey (Chair), Don Cossairt and Carter Ficklen (Members) for their participation on this year’s Nominations Committee.

 

I’ve also noted, besides the papers to be presented at the Accelerator Session, a number of Continuing Education Lectures and Professional Enrichment Program courses that will be presented by Accelerator Section members (all at the Sacramento Convention Center):

HPS Midyear Meeting Announcement

Mike Grissom

For nearly 3 years the Health Physics Society’s (HPS) Accelerator and Medical HP Sections as well as the Arizona Joint HPS/AAPM Chapter have been developing themes, family outing opportunities, technical tour candidates, and a draft Technical Program for the 2013 Health Physics Society Mid-Year Topical Meeting in Scottsdale, Arizona (January 27-30, 2013). That theme “Medical Health Physics and Accelerator Dosimetry” will be one of the few HPS meetings in the past several years to focus exclusively on issues that most impact the medical communities of the Society (including accelerators). In an effort to broaden the participation, a special effort has been made to have members of the American Association of Physicists in Medicine (AAPM) actively participate in planning and presentations at the meeting. Between the 3 sponsoring organizations in the HPS and the possible Co-Sponsorship of the AAPM (application for which was sent to the HPS Board of Directors for approval on June 6, 2012 and will be reviewed at the HPS Board Meeting in Sacramento next month) we are hoping to see well over 400 registrants at the meeting.

Proposed 2013 HPS Professional Development School in Albuquerque, NM Canceled

Mike Grissom

As was true for the 2013 HPS Mid-Year Meeting upcoming in Scottsdale, Arizona; for nearly 3 years the Health Physics Society’s (HPS) Accelerator and Medical HP Sections have been working on a companion HPS Professional Development School (PDS) titled “Topics in Accelerator Health Physics and Medical Applications.” After some effort to locate this PDS in the Phoenix area, it was decided to move it to Albuquerque, NM and the effort received excellent support from the HPS Rio Grande Chapter. Notably, Elaine Marshall (Sandia) volunteered to serve as the Administrative Dean and provided local arrangements services including scoping out the venues in the uptown Albuquerque area. Unfortunately, the Academic Deans (both of whom were under severe time constraints) were not able to prepare a firm Academic Program and faculty list in time to develop the required budget information portion of the PDS proposal package for approval by the HPS PDS Committee and HPS Board of Directors at the upcoming HPS Annual Meeting in Sacramento, CA as is required by HPS PDS Rules. Because of this, we’ve abandoned the 2013 PDS effort in Albuquerque. However, we have not abandoned the concept and we are exploring supporting this PDS as a companion program to the 2014 HPS Mid-Year Meeting in Baton Rouge, Louisiana (February 2014). Preliminary contact has been made with HPS Deep South Chapter members and local medical physics staff. If possible, a new proposal will be presented to the HPS Accelerator Section Board of Directors at their next meeting in Sacramento. I personally greatly appreciate the effort the Rio Grande Chapter persons made for this important endeavor and hope their efforts will be recognized by Accelerator Section members at Sacramento.

On Friday, June 18, 2012, the continuous electron beam accelerator facility (CEBAF) at Jefferson Lab completed its last 6 GeV nuclear physics experiments. Far from closing though, the Free Electron Laser is operational, the Polarized Electrons for Polarized Positrons (PEPPo) experiment is running in the injector, and the lab is undergoing a major refit to operate at 12 GeV that will take over 1 year to complete. JLab's fourth experimental hall (Hall D) construction is complete as is the tie-in to the CEBAF accelerator tunnel.

The accelerator portion of the upgrade will be constructed on the framework of the existing CEBAF accelerator. A 12 GeV beam to Hall D and up to an 11 GeV beam is needed for Halls A, B, and C. To achieve this, the accelerator will be upgraded to 2.2 GeV/pass (1.1 GeV/linac) and the beam transport system upgraded and expanded. Upgrades include:

Fermilab ALARA Project Description for CY 2011

Kathy Graden

 

At the Fermi National Accelerator Laboratory (Fermilab), a policy consistent with integrated safety management (ISM) and in accordance with 10 CFR Part 835 requirements is to conduct activities in such a manner that worker and public safety, and protection of the environment are given the highest priority. Fermilab is committed, in all its activities, to maintain any safety, health, or environmental risks associated with ionizing radiation or radioactive materials at levels that are As Low As Reasonably Achievable (ALARA). Likewise, Fermilab management supports related work planning and review activities in support of the Fermilab ALARA program.
