Supervisor: TT, with: JN
Log book#4 pages 32 - 37

Shift Summary:
------------------------------------------------------------
1. Power supply work until 20.30, then injection and 
   ramping..
   21.12: Beam stored and cogged at gamma=70.  Steering 
   for Phenix.
   22.12: Attempt to steer for Brahms.

2. Run 2144 from 22.14 to 23.27.  Varying scaler rates 
   (see logbook)
   Contains 477 collision events, probably good run!
   Interaction vertex seems to be at right place.  Tracks 
   seen in all 4 TPCs.
   T2b anode voltage raised from 1250 V to 1280 V before 
   starting run 2145 (still running.)  
   Some improvement in cluster quality.
   
3. No special problems (except MTPC2 and T2a anode wires 
   tripped once due to sudden beam injection during HV 
   shift check test, and T3 anode wires were found tripped 
   at the same time.)  Otherwise stable.
