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_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
|
CPP plans
|
- GPR with MLP (multilayer perceptron) learned prior, trained on GlueX-2020 + PrimEx2021
- Uncertainty quantification used to determine when to return to the comfort zone (3%: is threshold for standard_deviation_of_prediction/ideal_GCF)
- 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.
- CPP AIEC CONFIG

PrimEx 2022
|
Aug-Dec 2022
|
|
- Same model as for CPP
- GPR with MLP (multilayer perceptron) learned prior, trained on GlueX-2020 + PrimEx2021
- Uncertainty quantification used to determine when to return to the comfort zone (3%: is threshold for standard_deviation_of_prediction/ideal_GCF)
- Default HV 2125V
- HV predictions rounded to nearest 1V
- /group/halld/AIEC/utilities/CDC_control_ai/ cpp/d_cdc_modelneeds/gpflow_params.pkl
|
- HVB current is fixed at the value read during initialization
- ? RoboCDC switches itself off when the target is changed to empty?
