The Free Electron Laser (FEL) facility has gotten beam past the first superconducting half-cromodule, which has produced >5 MeV beam. Now this may not seem to be very much, but it was done very quickly due to the experience with "the big machine." They hope to have beam up to 40-50 MeV by January. One of the first experiments to be done will not actually be related to the lasing capabilities of the FEL. It will be an opportunistic irradiation of liquid ammonia in (separately) argon and liquid helium with the electron beam. The Radiation Control Group (RCG) will be taking this opportunity to make some confirmatory measurements of the integral shielding (i.e., the floor/ceiling between the accelerator vault and the user labs) and the penetration calculations.
We are running three experiments in the three experimental halls for the Continuous Electron Beam Accelerator Facility (CEBAF) on a regular basis now. Our main focus for the Accelerator Division (under which the RCG resides as a support group) is to increase the fraction of time for which the accelerator is available for experiments.
We went through the long ordeal over the last few months of putting out a competitive bid for our new dosimetry contract and have finally selected a vendor for the new year. This will involve us reapplying for DOELAP (Department of Energy Laboratory Accreditation Program) accreditation under the new vendor.
