5. STAR Comments on Higher Energy Collider Development and Collisions We’re currently ~ 10 wks past the start of the FY05 proton running (March 24th). We’re ~ 6.5 wks into the proton Physics run (April 19th). We have ~ 3.2 wks left in the run (June 25th, Question: Are we actually planning to end on a Saturday?). Our best week of the run so far, we sampled 30 to 35 nb-1 of FOM. If we get 3 more wks, similar or better than the best week, we’ll just reach our longitudinal pp goal of sampling ~ 180 nb -1 of FOM (currently at ~ 93 nb -1 ). Our goal of sampling 4 pb -1 of transversely polarized beams will clearly not be achieved this year. Discussions within STAR of whether to run transversely polarized beams for a modest number of days (e.g. 3 to 5) at the end of the run are taking place as we speak. As the Collider Physicists believed that this dev. work had to happen this year, STAR supported using up to 10 shifts (i.e. 8 am Tuesday May 31st to ~ 4 pm Friday June 3rd) to attempt to accomplish the goals in Mei’s “Energy Ramp” dev. Plan. This includes any running for the experiments. Success or failure, STAR wants to go back to the 200 GeV Spin physics running no later than Friday afternoon, June 3rd.
