The President's Message
Rich Brey

Greetings!  As president of the Accelerator Section of the Health Physics Society I would like to thank and acknowledge the extraordinary efforts of my two immediate predecessors: Mike Grissom and Linnea Wahl.  I personally marvel at the magnitude of work accomplished and the level of intensity with which these two individuals have engaged their responsibilities as president and past president of the Accelerator Section.  At times it has been a challenge to simply keep up with their e-mail exchanges let alone the many activities they accomplished.  I’m certain they will continue to be involved with the section and our profession in many ways for years to come.  Mike and Linnea; I salute you both.


One of the more exciting events planned for the near term is of course the 2013 HPS Mid-Year meeting in Scottsdale, AZ.  The plan is for the Accelerator Section to jointly sponsor this meeting along with the Medical Section of the Health Physics Society.  While there is a great deal of organizational work that has yet to be completed, the meeting promises to be valuable.  I look forward to the further development of this activity.

The Past President's Message
Mike Grissom

I hope all who were able to attend the 56th Annual Meeting of the HPS got back home safely from West Palm Beach, Florida. It was great to see so many of our Section’s members in attendance and the great participation (speakers and attendees) at the morning’s Accelerator Special Session “Neutrons from Accelerators” and the afternoon’s regular Accelerator Session on Wednesday, June 29, 2011. One thing that really jumped out at me was the great success the Accelerator Section had in the 2010-2011 HPS Awards year. At the Special Session, we had two G. William Morgan Lecturers (Don Cossairt, FNAL and Scott Walker, then of LANL now of BNL).

Publication of ANSI Standard N43.1 (2011): "Radiation Safety for the Design and Operation of Particle Accelerators"

James Liu

Scott Walker

The new ANSI N43.1 standard (2011): "Radiation Safety for the Design and Operation of Particle Accelerators" is published in December 2011.

The previous ANSI N43.1 standard was published for use in 1969 and covered mainly technical aspects with a stipulation that the standard applied principally to accelerators with energies less than 100 MeV. In 1974, a review of the standard was conducted that resulted in changes (principally dosimetric quantities) and a revised standard that was approved in 1978.

Updates to the Accelerator Section’s Website
Mike Grissom

A number of updates have been made to the Accelerator Section’s website since the 2011 meetings in West Palm Beach, Florida. As we near the time for nominations for the new Section Board of Directors slots coming open, it is well to recall who the past officers have been and who is on the current Board by checking out the Officers web page. Those officers whose names have “2012”¯ besides their names will be leaving the offices shown at July’s HPS Annual Meeting in Sacramento. I hope many of you will consider running for office in the next few weeks!

Proposed Changes to the Structure of the Accelerator Section Leadership
Scott Schwahn

Dear Colleagues,

In the last Accelerator Section Newsletter, I detailed some of the difficulties in getting nominees for the leadership positions in the Accelerator Section. The effort to put new officers in positions is an annual one, and having served several times on the Nominations Committee, I can tell you that it has never been easy! On two of three occasions, the Committee was unable to come up with at least two persons for each position, and I don’t think that was from lack of effort from the Committee. There is a distinct lack of interest in serving as an officer of the section.

I have suggested a change to the structure of the Section leadership, and the Section President has asked me to share the recommendation with you.

USPAS at Michigan State University June 18 - 29, 2012

The next U.S. Particle Accelerator School will be sponsored by Michigan State University and held in Grand Rapids, Michigan from June 18-29, 2012. One undergraduate course and ten specialized graduate-level courses are available.  Financial support is available but is very limited:  please submit a cover letter explaining why the USPAS is important to your career; your CV; and a letter of recommendation along with your application form.  Those not receiving financial support may audit their course. Participation is open to both U.S. and non-U.S. citizens. International participants not currently residing in the U.S. may apply to attend the program and may request financial sponsorship but they may not earn credit from Michigan State University.

Courses to be offered:
