   • Tracking / extrapolation to MWPCs Preliminary studies of extrapolation of FDC tracks to MWPCs

Comments to Response 2

• ERR Committee comments to response 2

Response 3

1. Preliminary results from cosmic-ray test in EEL126. 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 electronic noise that is under investigation.
   • Efficiency summary for Arwen and Denethor (retest)
   • Efficiency summaries for all chambers
   • Arwen R188 analysis and voltage scan
   • Bilbo R166 and Celeborn R169 analysis
   • Denethor analysis R184
   • Eowyn analysis R171
   • Frodo analysis R175
   • Galadriel analysis R157

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
