    • Walt is encouraged to submit the invoice for the electronic enclosures stating that they were delivered to Rory at UMass.
  5. AI for Experimental Controls testing during CPP (David)
    • There have been ongoing discussions on ow to implement the Control Feedback during CPP
    • There is a plan for a preliminary test during PRIMEX, lead by Naomi
    • The test during PRIMEX would start with manual evaluations moving toward a semi-automatic procedure.
    • The PRIMEX test will be good preparation for the "production" test during CPP
  6. MWPC Testing
    • FMWPC Log Book
    • Elton presented a lot of the information in recent log book entries.
    • Preliminary efficiencies are estimated at > 99.6%. So far we have looked at Haldor (with electronic enclosure) and Denethor (without electronic enclosure)
    • There are indications of noise hits along with signal, which we will continue to investigate.
    • The plan is to continue cycling through the chambers at JLab for an initial look at response and efficiency.
  7. hdgeant4 updates (Mark)
  8. TOF Trigger (Simon)
    • Are there tests that we wish to schedule during this run?
    • At or next meeting we need to develop a plan for any trigger tests that could use beam so that we can coordinate with Sasha.
