  2. BEMC timing scan rus ..60-..75

January 26 -----------------

emc-check run config is defined.

From Jeff:

(2)   I just updated the pp500_production file with thresholds for 
emc's/fms as per the 11am mtg today:    I followed the convention of 
leaving the parameter set to -1 (to pick up the default) where the 
default was correct, and explicitly set the value as needed.   For the 
FMS, I used Carls WAGs.   For the EMC's I used the 2009 thresholds...

FMS:   all the defaults are set according to Carls request in tier1 
file, so no changes.

BEMC HT to 11/18/25/31
EEMC HT:  25/31
BEMC JP & EEMC JP:  32/43/64
BEMC-EEC-overlap-JP:  32/43/64

February 5 -----------------

From Carl: C-AD says we could see an average lumi during a fill of 10^{32} toward the end of this run. Based on past history, we will probably see this luminosity, although our "average" will probably be less.

My current guesstimate from the RICH scaler rates that I've seen so far is that 10^{32} will correspond to a ZDCMB rate of ~330 kHz plus random coincidences.

L2ped changed, first new run 12049071

the following 7 BTOW towers which are already masked in L0 have been now masked in L2.

22:02 General They tried to put in AnDY and we lost the store

February 21 -----------------

Strong difference in lifetime of bunches, fill F15207, start at 5 am, end at 4 pm, see attachement

 

February 22 -----------------

Current RHIC fill=15213

RHIC Broadcast: Tuesday, February 22, 2011 
08:40 - 109x109p2 store with AnDY in Collision.
Next Polar meas at 13:15.
Dump scheduled for 15:50.

 

February 26 -----------------

Now that a number of gas-jet measurements are available for this year's run, it was decided at today's RSC mtg to start reporting p-carbon polarizations using the current best calibration for the correct averaged (over the beam profile) p-carbon analyzing power for 250 GeV. This means that we'll start seeing p-carbon polarizations in the mid 40% range.
