On shift : RC, NP
LOGBOOK #7, pag. 25-29  

Run at the chi_0 background (3470 MeV) with a constant luminosity of 
about 2 * 10^31 cm^(-2)s^(-1).
Beam stable (initial current 33.3 mA)

FEW PROBLEMS:

Scaler readout was wrong ( looking at the printout it was wrong since
April 5th). A broken NIM-ECL converter was found and changed. Now the
scalers are OK.

After every automatic stop and start run, errors on some drivers 
 "Failed to clear interval timer"

Jet was in regulating mode, but the density did not change. We then 
switched off the regulating mode and adjusted the density.

7 DAQ hangs, reset works OK for all cases.

LUMINOSITY SUMMARY
