Alternating Gradient Synchrotron
News from AGS

The AGS finished its polarized proton program in November. This 3 week run
came on the heels of a 12 week high energy proton program. After a two week
cooldown the Linac, Booster, main ring and target caves were surveyed and
opened up for maintenance. The operational schedule as it stands now is for
a four month shutdown followed by a six week heavy ion program commencing in
mid-March. The high energy physics program will immediately follow this,
and should continue for most of the rest of the year. One month will be
dedicated running time for the g-2 experiment, which ran for the first time
for five weeks this passed summer. The g-2 experiment uses a rotating
nickel target to produce 3 GeV/c pions. The pions are used as a source of
muons. It is the experiment's goal to improve CERN's previous measurement
of the anomalous muon magnetic moment by a factor of 20. The experiment
uses fast-extracted protons. The resultant prompt exposure rates outside of
the target hall were slightly higher than expected by our health physics
group. However, access is controlled, and the target hall is remotely situated.
On a political note, the Secretary of Energy, Federico Pena, announced on 25
November the selection of Brookhaven Science Associates (BSA) as the new
contractor to manage and operate Brookhaven National Laboratory. The
Brookhaven Science Associates team is led by the Research Foundation of the
State University of New York on behalf of the State University of New York
at Stony Brook and Battelle Memorial Research Institute of Columbus, Ohio.
BSA will replace Associated Universities Inc. which had managed the
laboratory since its beginning in 1947. BSA will have a 5 year
performance-based contract with performance measures in science and
technology, environment, safety and health, and community involvement.
