We have summarized the preliminary results from the cosmic-ray test in EEL126 in [https://halldweb.jlab.org/DocDB/0053/005373/002/MWPC_production_testing.pdf '''Production Testing of MWPCs for CPP''' (GlueX-doc-5373)]. The CPP experiment requires six MWPCs and we have six chambers that deliver excellent performance in the cosmic-ray setup in the EEL. The estimates of the efficiency are of the order of 99.7% or greater over a broad range of voltage and/or software thresholds. Two spare MWPCs (Frodo and Galadriel) exhibit low levels of electronic noise that is under investigation.

Response 3

We have summarized the preliminary results from the cosmic-ray test in EEL126 in Production Testing of MWPCs for CPP (GlueX-doc-5373). The CPP experiment requires six MWPCs and we have six chambers that deliver excellent performance in the cosmic-ray setup in the EEL. The estimates of the efficiency are of the order of 99.7% or greater over a broad range of voltage and/or software thresholds. Two spare MWPCs (Frodo and Galadriel) exhibit low levels of electronic noise that is under investigation.

Comments to Response 3 (Approval)

  • Email from Patrizia: The main points are summarized in the next two points.
  • "...the committee is satisfied with the results of the MWPC tests and therefore they think the CPP/NPP collaboration fulfilled the requirements to pass the ERR."
  • The committee encourages us to measure the performance in Hall D: "...the noise level can be different in the hall and therefore the threshold settings that will affect the efficiency. A test of chambers in the hall before the run is advised."

Additions to Standard Equipment

The major modifications required to operate the experiment are the following

  • Design, fabrication and installation of the muon detector
    • Multi-wire proportional chambers
    • Modifications to the downstream platform, support structure and iron absorbers
  • New (mono-isotopic) solid Pb target
  • Charged-particle trigger based on the time-of-flight detectors
  • Move tagger microscope to cover 6 GeV coherent peak
