DAY shift / S. Sirca (SL), H. Yao (TO), M. Mihovilovic (3rd)

============================================================



Momentum changes for left HRS are listed among the runs

Momentum changes for right HRS are listed among the runs

as well as in the main section



Main

----



08:01  started to change right p to 698.895 MeV/c

09:02  LHe target (loop 1) vented, controlled access

09:30  LHe target (loop 1) recovered

12:15  started to change right to 651.627 MeV/c

13:18  started to change right to 566.465 MeV/c

14:13  beam current reduced to 30uA per RC's request

       (wanted to have ps3 on left arm less than 4)

15:59  beam is back at 25 uA which we take on LH+Pb target

       and pass it on to the swing shift

Comments

--------



(*)  Redo Left HRS runs on Fe while waiting for target expert

     and because Right HRS needed to be completed as well.



(**) During run 20579 (651.627 MeV/c on He), several computers

     crashed due to problem with the crates in the middle room.

     After Ole recovered the systems, /adaql1/disk2 contained

     the 20575 data file (which is good and labeled correctly),

     while /adaql1/disk3 contained 20575 as well (which should be

     20579 if the DAQ hadn't crashed).  Manually moved 20575 on disk3

     to 20579 (which is what it should have been), then manually

     adjusted the DAQ to start with 20580.  So effectively 20579+20580

     are good runs in the same setting.
