FYI update on rhic plans, more or less alomng the lines I already send to you ---------------------------------------------------------------- Flemming Videbaek Physics Department Brookhaven National Laboratory ====== Scheduling Physicist -YIP (ie. SPY) news channel ======== (1) The usual Time meeting will be held at 13:30 on Feb. 24 (Tuesday), 2004 in the Snyder Room (911A). ****************************** **************************** (2) Main schedule item this week : Wed. (Feb. 25): 06:00 - 18:00 Beam Expts. Thur. (Feb. 26): 09:00 - 16:00 Machine Development which may be cancelled or shortened. On Thursday, Haixing et. al. will install electronics for the polarimeter in the AGS behind a RHIC store. Moreover, the polarized-proton AGS run will start this Thursday (in preparation for the RHIC polarized-proton run). ****************************** **************************** (3) 4.5 hours => 3.5 hours To optimze our operation further to improve luminosity, we have set the store length to the following manner (from the previous 4.5 hours): if ( ! PHOBOS_background ) // i.e., if there is no PHOBOS store_length = 3.5 hours // background problem else // ie. if PHOBOS background store_length = 4.5 hours // problem does exist endif We'll re-evaluate next week to see whether this works well. The polarized-proton team and NSRL (NASA) both actually would probably prefer a longer store length. ****************************** **************************** (4) Brief status in my view: We again have had another weekend with the greatest luminosity collected so far. The increased bunch intensities ~ 1.1*10^9 proton per bunch more than compensate for the reduced bunch numbers. Experiments seem to be OK with this mode for the time being. The LINAC (Linear Accelerator) has run with beam since last week and I was told that they start sending beam to BLIP (Brookhaven LINAC Isotope Producer --- I bet not many people know this abbreviation) as early as today. I have received a very colorful schedule for the NSRL-2 run which is currently said to run from Mar. 15 to Apr. 22, 2004. There are many many expts. ........ Hmm ...... In this morning's Injector (AGS/Booster) meeting, people have started to come to grip with the reality of multi-purpose running ----- it's very hard ! ====== ======= ====== ======= ====== ======= ====== ======= This SPY news channel solicits YOUR input of any sorts.
