Commissioning Goals
- Integrate DIRC readout with general Hall D DAQ and online/offline monitoring
- Calibrate per-pixel timing offset of MAPMTs using LED system
- Determine geometric alignment parameters (position and angle offsets) for optical components
- Implement reconstruction algorithm and compare data/MC: # detected photons, Cherenkov angle resolution
Commissioning Tasks and Milestones
- TBD

Datasets to acquire with integrated DAQ
HV and threshold scans
- Similar set of HV, MAROC gain, and threshold settings as laser setup for comparison with final implementation
- Validate MAPMT characterization with both LED calibration and beam data
Intensity scans
- Evaluate rate dependence and backgrounds for both high and low luminosity
- Scans of fixed amorphous radiator and varied current from 50 - 300 nA
Simulation studies for commissioning
Requirements
- Final geometry in CCDB with appropriate run number
- Define JANA calibration variation for CCDB specific to DIRC(?)
- LUT algorithm implemented as factor in DIRC sim-recon library
Data Samples
- bggen sample (1M events) for comparison of rates and occupancies with data
- single track pion and kaon samples in kinematic bins for comparison with data
