Dear Collaborator, Let me first wish you happy Holidays, and thanks for the effort in the last year to bring several important Brahms results to the publication and presentation stage. I hope this also sets the forum for the upcoming run and analysis of data from both d-Au and pp running. On the immediate progress the experiment is being prepared for the run. As you know from the collaboration meeting improvements to TPCs and DC has been done. All detectors in use last year have been checked out and are ready. The trigger counters both for MRS and FS and been installed. The VME electronics that will allow to setup an efficient MRS and FS triggers was delivered Friday and are in final checkout phase. The new C4 cherenkov detector for MRS is not as far as hoped for earlier this year. Though now the full assembly has been rather succesfully tested against leaks at Kansas and has been shipped to BNL. It will probably be in the order of another month before the detecor will be installed on the MRS platform. The accelerator is making steady, but slow progress toward beam. Deuterons have been accelerated to full energy, the rapid switching (~9 minutes between Au and d) at the injector level is standard, but successful ramps with both beam and collision have yet to be achieved. The plan/prospect is that collisions will be achived in the next few days, and by the end of the week (Friday?) stores with 56 bunches of d/Au albeit with limited luminosity will be given over to the experiments for longer periods ( 10 am- morning.). Thus some of us will start working toward commisioning the triggers, detectors, and monitoring software It is still hopefull that a physics run with overall priority for the experiments can start early January. best regards Flemming -- Flemming Videbaek Brookhavne National Laboratory Physics Department tlf 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov
