The President's Message
Kamran Vaziri

Our annual technical session will be at 10:15 AM on Tuesday, July 15, at the Health Physics Society (HPS) annual meeting in Pittsburgh, Pennsylvania. The business meeting of our section will be at the end of the technical session. Please plan to stay around for the business meeting that starts at 12:00 noon as your board of directors values your input.

This year’s election committee consisted of Don Gregory from Oak Ridge National Lab and Michael Duran from Los Alamos National Lab, and the committee was chaired by Past-President Scott Walker. We had good member participation. We received more that twice the number of last year’s votes. The results will be certified and finalized at the Accelerator Section’s business meeting.

The Editor's Message
Linnea Wahl

This issue of the newsletter brings sad news of the death of Tony Sullivan. In his honor, his friends have prepared a brief review of Dr. Sullivan’s many scientific accomplishments and contributions, which attests to the fact that he will be dearly missed by his colleagues in the accelerator health physics community around the world.

Also in this issue, Accelerator Section President Kamran Vaziri reminds us that another year has passed and a new board of directors will begin their term directly following the annual section business meeting in July. Among the new officers will be a new newsletter editor. I can’t name any names, but I know you’ll be pleased with what you see in the next issue. Please start thinking now about the articles you want to submit for the inaugural issue under new management..

OTHER NEWS

In Memory of Tony Sullivan

We are saddened to report the death of the distinguished dosimetrist Dr. Anthony Hayes Sullivan on Monday, May 26, 2008. He died in Worthing Hospital, West Sussex, at the age of 75 after a protracted illness.

Tony Sullivan was born in 1933 in Slough, England. After leaving Sir William Borlase’s Grammar School in Marlow, Tony studied in the evenings at the Battersea Polytechnic Institute (forerunner of The University of Surrey) for a University of London degree in physics, while working during the day for a local engineering company. He earned an honours degree – always a significant achievement but particularly for a part-time student. He then accepted a position at the Atomic Weapons Research Establishment at Aldermaston where he was required to measure radiation from the Christmas Island atomic bomb test series (mid-1957). Later that year (October) he observed the dosimetry carried out during the Windscale Nuclear Reactor #1 fire.The I-35W bridge that collapsed Wednesday, August 1st was very close to the School of Physics and Astronomy's Williams Laboratory, known as the "Tandem Lab." The bridge was twenty feet from the building's loading dock. There were no University staff, faculty, or students in the laboratory at the time of the collapse.

A Glimpse of Things to Come

For those who haven't yet decided whether to attend the annual Health Physics Society meeting next month in Pittsburgh, Pennsylvania, here is a glimpse of some of the talks slated for the special accelerator session on Tuesday morning, July 15. This promises to be another great session, so plan now to attend.

FROM THE CORRESPONDENTS

News from Spallation Neutron Source, Oak Ridge National Lab
Don Gregory

The Spallation Neutron Source (SNS) is in the midst of a 3.5-month run cycle. During the last year, the project has pursued an aggressive ramp-up of proton beam power on the mercury target. A record power level of 500 kW (protons on target) was achieved during this run period, and routine production is in the power range of 400 to 500 kW. Improving operations reliability will be the primary emphasis for the next year or so - the beam has been on-target approximately 75% of the planned hours so far this year. Accelerator physics personnel will also work on reducing losses in preparation for higher-power operations in future years. Three research instruments are accepting outside users at present, with another three instruments approved for use and concentrating on calibration activities and measurements involving "friendly" collaborators.
