On Shift: JK,GG
Log Book #8 Pages 172-176

Run Summary:

Chi0 (3400 MeV)
Beginning Current : 13.6 mA
Final Current     :  8.8 mA
Typical Luminosity: 2x10^31 cm^-2 s^-1
Typical Beam Width: 1.2 MeV/c

Run    Lumiosity
5913   291.4 nb^-1
5914   291.9 nb^-1
5915   Overwritten (see below)
5916   pedestal run
5917   pedestal run (this time with gas jet off)
5918   given to evening shift


Comments:
5 jet nozzle unclogs (since we are running so close to the saturation point).
 
12:40  Found that one of the FCAL shaper boards had stopped working. TV & SS
       came in to look into it.
       
13:15  Gas Jet turned off (still trying to fix the shaper)

14:00- MG comes in to help. With help from Michelle via the telephone, GG
14:47  replaced the shaper fuse. The FCAL shaper board
       power supply was then power cycled. The board tested ok so the paused run
       (5915), which had only a few events, was overwritten, pedetals were
       taken, and data taking was resumed.
       
14:55  FCAL channels 13 (on the fixed shaper board) and 114 (not on the fixed
       shaper board) are dead after the fix. The signals are seen on the shaper
       inputs, but not on the outputs. 


Good afternoon,
