Tune

Determine if the Beam Left Scintillator is linear with beam current.

run#	FC1	Scint Left (Ch9)	Reprate	start	stop	Int Rate	comments
3696		2335		17:30:08	17:31:39 ( s)	11 events/s	first measurement at full current
3697		59		17::	17:: ( s)	events/s	cut the current in half
3698				17::	17:: ( s)	events/s
3699	100 px			17::	17:: ( s)	events/s

1. T1 out, disable D1, send the beam to FC0, take scope image of the area.

2. T1 in, enable D1, bend the beam by 90 deg, take a run with 1000 events.
