Installation and Commissioning

Back to 2017 Fall Run Plan Back to Tritium-Main

Before Beam

• Trigger Timing Checkout (placeholder slides)
• HRS Detector Checkout
• Beamline
• Spectrometer Angles
• Magnets
• DAQ
• Software

With First Beam

1. Beamline
   1. Beam Centering
   2. Raster Size Calibration
   3. BPM Calibration (pedestal run, Bullseye scan)
   4. BCM Calibration
   5. ARC Energy Measurement (parasitic only)
2. Trigger Timing Checkout
3. Detector Checkout with single foil, multi foils, and target cells
4. HRS Optics with saturated Q1 (LHRS p0>3 GeV, RHRS?)
5. Boiling Study at 17 degree on 3H, 3He, 2H, H targets and empty cell
6. Detector Calibrations (in parallel with other activities once we have the electron data)
