FROM THE OFFICERS
The President's
Message
Kamran Vaziri
The 2007 annual
meeting in Portland, Oregon, was a very busy time for the
Accelerator Section officers. Starting Sunday afternoon we had daily meetings
with the Northern California Chapter of the Health Physics Society (NCCHPS) and
the Health Physics Society (HPS) Program Committee members, HPS secretariat,
and other HPS committees and officials. Although a lot had been accomplished
since the 2006 annual meeting, there was a lot more left to do. read more
The Past
President's Message
Scott Walker
The agenda for the 2008 midyear meeting of the
Health Physics Society (HPS) is progressing rapidly. Several world-renowned
speakers have agreed to present either at the plenary session or to act as
keynote speakers for the meeting sessions. In addition, we have obtained a
full agenda of experts to present the professional enrichment programs (PEPs) and continuing education lectures (CELs). Here's a sneak preview of the planned agenda. read more

INVITED PAPER
2007 G. William
Morgan Memorial Lecture: Radiation Safety around High Energy Particle
Accelerators
Anthony H. Sullivan
Looking back on a career of being responsible for radiation safety,
involving many types of accelerators, this paper describes incidents that
happen in radiation protection that cannot be reasonably anticipated but
might with avoided by imaginative thinking and some understanding of human behaviour. This lecture discusses improvements necessary
in procedures, hardware, and beam dynamics which, if rigorously implemented
throughout the accelerator world, in all accelerator areas, independent of
the place or accelerator type being used, would ensure safety measures of a
uniformly high standard..." read

2008 MIDYEAR & SCHOOL NEWS
Abstracts to Whet Your Appetite
Linnea Wahl
If you've been wondering whether to attend the 2008 Midyear
Topical Meeting of the Health Physics Society (HPS), here's a
sneak preview just to whet your appetite. The following abstracts from the
upcoming meeting were chosen at random from the more than 120 abstracts
received to date. They represent just a small portion of the many fascinating
talks on a broad range of radiation-generating device topics that you will
hear at the midyear meeting. Hope this sampling convinces you that the
midyear meeting in Oakland
in January 2008 will be well worth your time! read more
School Registration Now Open
Linnea Wahl
Registration for the 2008 Health Physics Society (HPS) Professional Development School,
"Topics in Accelerator Health Physics," is now open. The registration form is
available on-line and in the September issue of the HPS newsletter, Health
Physics News. read more
Scholarship Available for 2008 Professional Development School
Linnea Wahl
We all remember our student days well--cutting
corners, eating sparsely, living cheaply. To a student, an offer of financial
help is a great opportunity that often opens doors. That's why we're proud to
announce that there is a scholarship of $1200 available--thanks to the
generosity of Dr. Ralph Thomas, who donated several rare books toward the
cause--for a student in accelerator health physics. The scholarship will
allow a student to attend the 2008 Health Physics Society (HPS) Professional Development
School on "Topics in
Accelerator Health Physics" from January 31--February 2 in Oakland, California.

FROM THE CORRESPONDENTS
News from Fermi
National Accelerator Lab
Kamran Vaziri and Don Cossairt
At the
time of this writing Fermi National
Accelerator Lab's (Fermilab's) 2007 shutdown,
which started August 6, is in full throttle. The coordinated effort started
weeks before the actual shutdown started. Original ALARA planning of several
major jobs predicted the total shutdown dose of several tens of person-rems. With the help of some preliminary surveys and
careful planning of the schedules, the total accrued dose as of today, about
three weeks before the end of shutdown, is 5.9 person-rems.
In addition to an enormous amount of maintenance, the main projects are
replacement of the pi-shaped power poles and installation of collimators and
new corrector magnets in the Main Injector and Booster accelerators. read

News from the Spallation Neutron Source,
Oak Ridge National Lab
Don Gregory
The Spallation Neutron
Source (SNS) is currently in its third outage period, and the transitions
between operations and maintenance continue to become smoother. The work
during this six-week outage includes repairs to one or two cryomodules (depending on what is found during diagnostic
tests) and a rather large effort pulling cables. As has been true in the
past, we have little or no history at performing these jobs and pre-outage
dose estimates are difficult (local dose rates, man-hours, and exact
locations of the work area are all uncertain for different reasons). For
purposes of maintaining doses as low as reasonably achievable (ALARA), most
of the higher-dose jobs have been scheduled late in the outage to take
advantage of decay - this also allows more time for planning based on measured
(rather than projected) local dose rates.
