- 193294 02/15/07 02:50 R. Feuerbach VDC inefficiency for B4C
Noticed that for run 6407 the VDC inefficiency was ~10% at the elastic peak, and the ratio of 5 hit:10 hit events had shrunk to 7:1.
Dropped the beam current to 0.4 microamps, the limit where we still can see something from BPMB for run 6408.
