Return to List of Daily Run Plans

Shift Duties

• Take Production data
• Log all issues, alarms and questions.
• Perform shift checklist.
• Log target status twice per shift.

Production Running

Take 1 hour runs for both Left HRS DAQ and Right HRS DAQ. Follow Kinematic settings for DVCS Kin_60_1 and GMp 4th Pass "Parasitic" Kinematics, summarized below:

Beam current	10 μA
Beam Energy	8.5 GeV
Target	LH2 (Loop 2)
Raster	ON (2x2mm2) [MCC units h=2, w=3]
VDC HV (both arms)	ON
DVCS Calo HV	ON

DVCS Kin_60_1

DVCS Calo Angle	15.89°
DVCS Calo Distance	1.5 m
LHRS Polarity	Negative
LHRS Momentum	3.594 GeV/c
LHRS Angle	24.564°
LHRS Q1 Current	749.67 Amps (regulator OFF)
LHRS DAQ Config	DVCS
prescaleL	PS9=1 (all others zero)

GMp 4th Pass "Parasitic" Kinematics

RHRS Polarity	Negative
RHRS Momentum	1.804 GeV/c
RHRS Angle	53.475°
RHRS DAQ Config	RHRSadaq2
prescaleR	PS1=PS2=PS3=1, && PS8=100 (all others zero)

Compton runs

Stop/Start a Compton run every 2 hours - The Compton DAQ is running on the COMPTON computer located in the back room in the Hall A counting house (the room with food)
