Dear Collaborator, I will not attempt to summarize the RHIC retreat that took place over the last 3 days. I attended a good part of Monday and this afternoon's sumamry sessions. All talks can be found via the CA-D home page. Let me though briefly mention a few point that are important for the upcoming runs. a) Choice of species. - The thought form each exp was base on the 31 weeks guidance - Phenix: 200 GeV Ni + 200 GeV pp 10+10 weeks physics running- since the goals for e.g. J.psi can be obtained in less thatn 10 weeks there were suggestions for alternate running e.g Ni at 240 GeV (due to lower Z/A) or assymetric Ni+Au - STAR 200 GeV Cu+Cu followed by 200 GeV pp - Phobos 200 GeV Si, + 1-2 weeks 63 GeV si + 1 day 19.6 GeV si -Brahms Since we have not made up our mind we mentione a) lighter Beam species (si,or Cu) + enough pp to do Ann measurements b) a wish to have additional 62 GeV running Outlook: It seems like LI ~9-10 weeks + pp at 200 for another 10 weeks, detaiuls pending on the RBUP b) The startup plans for experiment is cooldown October 1 !!! => beam setup 10/15-10/30 => ramp up 11/1-11/15 (i.e beam dev + exp at owl shifts0 ==> physics running start on or about 11/15 with ` 10 weeks HI ending on ~ Feb 1 3 weeks pp setup 2 weeks rampup + ~ 10 week beam -> May 1 Outlook: Run-05 will start mid-November much earlier than last year. Be prepared both for an early setup as well as for taking shifts. c) a few misc items that has implications for work, operating - strong desire to go to store length.. that are determine by MCR and not by voting - desire from CAD to have more control over ZDC's - - desire from MCR to have vertex (longitudinal information available) - desire to have a drop-dead day (befire startup) after which no significant IR work can take place. regards Flemming ---------------------------------------------------------------- Flemming Videbaek Physics Department Brookhaven National Laboratory e-mail: videbaek@bnl.gov phone: 631-344-4106 _______________________________________________ Brahms-l mailing list Brahms-l@lists.bnl.gov http://lists.bnl.gov/mailman/listinfo/brahms-lReceived on Wed Jun 9 19:55:09 2004
