Hardware, configuration changes during Q-Weak running
November 5, 2010: First photon detector removed: (log entry). The second one must have been installed the same day or shortly thereafter.
November 19, 2010: Mark added 1 mm of lead in front of the photon detector: (log entry).
November 29, 2010: Busted laser safety box: (log entry).
December 7, 2010: Replaced Arshak's paddle with Moller scint. (log entry). I believe a second scintillator was hooked up to channel 11 at the same time.
December 8, 2010: Locked cavity in opposite laser helicity (log). Can't find log entry about restoration of original helicity - I'm pretty sure it was the next day.
December 9, 2010: Removed gamma-det. HV from patch (log entry)
