  1. CSC update – my random summary •  TMB 3.3v supply on peripheral crates –progress! •  CSC singles to be turned off • Were becoming a pain, e.g. bad timing for halo muons •  CLCT muonic timing to be implemented soon •  HLT (L3?) eff. Loss: •  Situation still unclear • ~4% according to some studies • Zm+m- cross-sections low relative to e+e- by >10% • for CSC/DT overlap and CSC-only regions •  CSC-TF charge still apparently wrong at GMT • Might be related to previous problem due to bad extrapolation of tracks? • Believed that CSC-TF “core firmware” has convention backwards, but don’t have support (?) for multiple core versions… plan is to : • Flip in “wrapper” and simultaneously in CSC-TF unpacker software. • Alex M. at CERN for 2 weeks, to work with Gian Piero and Laria on support for multiple versions…

  2. CSC nagging concerns I • Neutron scan special run – when L high enough… • ALCT time bins • Data compression? More early time bins? • Changes to data structure • ALCT timing information from Chris  DIGIs? • Mini-scope etc. in TMB • Allowed now for future CMSSW version 3.9 ?? • Improved documentation • General muon DPG detector performance article? Might naturally break into 3 papers, but preferably not. • CSC synchronization article • Twikis, especially on timing, online changes • Storage and tracking of firmware versions ALCT, TMB, CCB, MPC, DDU, DCC, CSCTF, VCC, etc.

  3. CSC nagging concerns II • Triggers & datasets: where do all of these go? • Single high-Pt triggers and datasets • Onia triggers and datasets • Single low-Pt (e.g. b physics) triggers and datasets • Halo muons • CSC activity triggers • Everyone sees a “piece” of the puzzle… • Would like to assemble known information… • Are we missing anything? • Need to improve DIGI information on timing, e.g. CSC anode timing?

  4. CSC upgrade •  Dick Loveless replaces me for CSC upgrade • Technical Proposal muon section in decent shape, maybe more verbiage on physics justification • David S. and Taylor to work on actual justification during Fall • Upgrade ME4/2: • Panels via CERN – try for sole-source procurement • Upgrade ME1/1: • Friday 11 a.m. EVO meeting on DCFEB
