Dear Chamber Folks;
A couple of announcements:
1) We are having a review of the gas system on Nov. 6 and 7. The review committee
will consist of Reinhard Schumacher, Larry Weinstein, Howard Fenker from the
CEBAF detector group and Graham Smith from Brookhaven, chaired by Howard.
Presentations will be made by me, Wayne Major and George Jacobs.
2) We discovered a problem with the Reg. 1 pulsing system. There is a polarity
mismatch between the pulse to the STB board and the STB SIP assembly. We are
considering rewiring the output transformer on each connector of the ADB
board (6 connectors x 72 boards).
thats all for now, Mac
