Experiment Date Wiki & reports Model Other details
PrimEx Oct-Nov 2021?? PrimEx_instructions
  • GPR, trained on GlueX-2020
  • Default HV 2125V
  • HV predictions were rounded to nearest 5V
  • Shifters ran the scripts to read EPICS and suggest HV, before setting HV and starting the run
  • Much of the run was with empty target. Shifters were not supposed to use the AI w empty tgt but they did.
  • The shifters were not asked to set the HV to 2125V before running the AI. This was not ideal, but saved time.
Cosmics March 2022 Cosmics_test_plans
  • GPR, trained on GlueX-2020 + PrimEx2021
  • Default HV 2130V
  • HVB current fixed at 9A
  • Temp fixed at 299K??? at start of run
  • HV predictions rounded to nearest 1V
  • RoboCDC ran autonomously, setting the HV every 5 minutes.
  • Half of the CDC was kept at fixed default HV.
  • Temp fixed at 299 or 300K until FDC LV brought temp into trained region
CPP June 2022
  • Linear regression with Bayesian learned prior???, trained on GlueX-2020 + PrimEx2021
  • Uncertainty quantification used to determine when to return to the comfort zone (3%?)
  • Default HV 2125V
  • HV predictions rounded to nearest 1V
  • /group/halld/AIEC/utilities/CDC_control_ai/cpp/d_cdc_modelneeds/gpflow_params.pkl
  • RoboCDC summoned by DAQ 'GO' to read EPICS and set HV.
  • RoboCDC scaled the HVB current reading to what it would have been at the default HV, before predicting GCF.
  • Overall on/off switch added to CDC HV control gui.
  • running exactly once at run start with a control window of [2110.0, 2150.0] Volts.
  • trailing epics window of 15 (seconds)
