FYI This gives you some up to date info on AGS and RHIC operatiuons cheers Flemming ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory tlf: 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov ----- Original Message ----- From: "Todd Satogata" <satogata@bnl.gov> Sent: Tuesday, May 22, 2001 8:49 AM Subject: Time Meeting 1:30 PM Tuesday May 22 > Hello all, > > This is a reminder of a Time Meeting this afternoon: > > Date: Tuesday, May 22 > Time: 1:30 PM > Place: Snyder Seminar Hall > > Final RHIC PASS Roll-ups are currently awaiting line crew maintenance > to close a required breaker in the C47 substation for A-line fan house > and D-line security problems, with contract workers not starting until > 0830 and roll-ups expected to complete before 1000. Last evening Au > beam was circulated in the AGS, with work focusing on Booster to AGS > synchro and injection. RHIC rings were also swept overnight, with a > few gates requiring mechanical attention. The RHIC rings and experimental > areas will still be accessible during days through the week, for final > setup, power supply checkout/final install, and cryo thermistor tuning. > > RHIC cryo cooldown is expected to have the blue ring at stable > operating temperatures late today, somewhat delayed due to a > late-night transient in the compressor room that has since been > stabilized. Blue ring He delivery has gone according to > schedule. Power supply switchover is on double crews and is also > expected to be completed late Tue May 22, pending determination of > impact due to PASS roll-ups. > > Siemens repair work completed a sling test mid-day Mon May 21, and > balance looks good. The are expected to be available for Siemens load > tests early next week, but this load switch and test will be scheduled > to accomodate RHIC beam setup. > > Barring unforseen circumstance, beam operations of the complex > (Tandem, Booster, AGS, RHIC if feasible) are expected to run through > the Memorial Day weekend, and the current beam schedule for upcoming > weeks will be shown and discussed at the Time Meeting. > > -Todd > -- > --------------+-----------------------------+----------------+------------ ----- > Todd Satogata | BNL C-A Accelerator Physics | (631) 344-5826 | satogata@bnl.gov > --------------+-----------------------------+----------------+------------ ----- >
