1. g14b: run started week ago, following problems were fixed:

• level2 cables connected under the CLAS

• several above-FASTBUS fans replaced, will continue

• rate was 4 kHz at 85% livetime at 20nA beam current BEFORE level2 fixes, expecting improvements

• cmon works in electroproduction mode, see target; will calibrate and switch to photoproduction

• DC noise problem was investigated, Mac found and removed aluminum foil inside region 1, hopefully it will help
