Presentation Transcript

  1. Stuff going on… • Data taking shifts began Monday 16 March during evenings until full CSC shifts begin 15 April • Lots of commissioning conflicts with RPC work, CMS infrastructure work… there is no end to these conflicts in sight… • Commission by day, take data by night… • CSC Track Finder has updated their FPGA’s to Virtex 5 chips… • Long Sunday for them… • CMS week ongoing • Bora Akgun (CMU) gave Commissioning talk at EMU meeting • Laria Redjimi (Rice) gave CSC trigger primitive talk at L1 trigger meeting G. Rakness (UCLA)

  2. Meeting discussions • Lots of discussion at IB meeting about moving towards sharing shifts with DT and RPC • Richard Breedon is going to talk with their respective operations managers… Plan to be presented within a month. • At L1 trigger meeting, RPC folks reported “minimal latency applied” in 4 – 5 March MWGR Run 7723… • I am running over it now to look for position of RPC data in TMB FIFO • I plan to re-measure communication parameters at next week’s MWGR  currently I don’t know which chambers have cables plugged in well… :-/ • Discussion with Darin, in the context of SLHC studies by V. Khotilovich… The question came up: • Assume a new muon (or muons) traverse a CSC every bx… what does TMB do? • The simulation is saying that the CLCT’s which are selected are often from the wrong bx… G. Rakness (UCLA)

  3. Some more stuff • In latest online software release (EMUlib v7.0), bug was found in writing to the TMB userPROM • Introduced when I expanded the TMB VME addresses to include addresses > 0xFF • Am working on it now… • When done, I should be able to also change how the userPROM’s are written according to updated ALCT state machine • The test setup at 904 is still not working  essential problem now = TTC crate… • Need Andre Holzner to fix it when he gets back from Italy… • At CRAFT workshop last week in Torino, M. Schmitt showed a plot of CLCT efficiency which has made it to the top of Building 40… G. Rakness (UCLA)

  4. Transparency shown at Plenary Commissioning Session Today… This is inconsistent with MTCC data which had >99% efficiency  I continue to request them to use exactly the same cuts Is this unreasonable? G. Rakness (UCLA)

  5. 25 – 26 March MWGR coming up… Goals… • Fully under XDAQr7 • Use Configuration database • FED crate • Monitoring back in place • DDU and DCC firmware upgrade • Track Finder • Memory leaks fixed • Understand why an extra Resync is needed at the beginning of run • RPC integration • Measure communication parameters on all available chambers… Anything I am missing? G. Rakness (UCLA)

  6. To do • Fix userPROM writing bug in CERN software • Get the TMB – ALCT loopback software going here at CERN… • STILL frustrated with self for not getting it going • Sidelined by finding the TMB userPROM bug • Obtain “CLCT key-wiregroup” finding program from Andy Kubik to derive how I should load TMB firmware to ME1/1 chambers G. Rakness (UCLA)
