Took BLAST field off data until 12:30 (runs 2564-2588 are all field off, some D2, some H2). Runs have NOT been lrn'ed -- too many wire chamber hits, lrn was not able to analyze at any decent rate.
Opened hall at 12:30. Another layer of mu-metal was added around the beam pipe where the BLAST coils neck together. Controls people are looking at the problem with the longitudinal holding field coils/power supply. Doug has found a broken wire in the left outer chamber (causing L23,24 to trip) and is fixing it.
Plan is to wait until tomorrow (9/16) to reverse BLAST field. Hall should be open for 7:30am.
