1. 21-Jan-2009CSC - ESSC Jan'091 Report on CSC for ESSC Prepared for CSC by Fred Borcherding FNAL

2. 21-Jan-2009CSC - ESSC Jan'092 CSC Electronics Status Conducted a Work Shop at Rice U in Houston January 8 th through 11 th –Description: –What problems were encountered during running? Of those, what have been fixed What the plans to fix the remaining problems What resources, (people, material, time) are needed to resolve the problems –What improvements should we make (as distinct from fixing problems) What are the plans? What resources are needed to make the improvement? –Maintenance Estimate For each module, how many do we have? How many spares do we have? Where are the spares? What level of engineering effort is needed to maintain the element? –Indico Link > http://indico.cern.ch/conferenceDisplay.py?confId=48204

3. 21-Jan-2009CSC - ESSC Jan'093 From CSC Q4’08 Report Short Term detailed Milestones and deliverables. Resolve issues with the operation and control of the Maraton power supplies Identify and fix outstanding Canbus issues Finalize optimal power-on and power-off sequences. Replace faulty resistors in HV system Investigate losses of communication between HV system and PVSS Reduce rate of CRC errors in DAQ system Develop a loopback test between the TMB and ALCT to allow the testing of the skew-clear cables between the chambers and peripheral crates. Further analyze the loss of programming of EPROMs Identify and correct problems with alignment system picomotor control

4. 21-Jan-2009CSC - ESSC Jan'094 LV Resolve issues with the operation and control of the Maraton power supplies –OPFC Failure of ON/OFF switch –Quick disconnect in input power circuit fails –With CMS working with Wiener on a fix Failure upon power on – Soft Start Issues –Turning on too soon after power off greatly increases possibility of failure –Administrative controls have been put into place –Hardware change begun Lack of remote monitoring and control –With CMS working on modification to add remote Identify and fix outstanding CANBus issues –CANBus for Maraton system Expect new server from Wiener Work to analyze CANBus lines to find and fix any deficiencies Start now, intensify when LV back on, work until resolved –CANBus for PCMB system > remote ON/OFF at pcrates > uses ELMB’s Work to analyze CANBus lines to find and fix any deficiencies Work with ELMB experts to resolve further issues Start now and work until resolved

5. 21-Jan-2009CSC - ESSC Jan'095 LV cont. Finalize optimal power-on and power-off sequences. –Observe several issues that have been reduced by a more complex power-on sequence –To proceed further we need to combine slow control of CANBus devices and VME devices –Work will start with availability of cooling and CMS LV in cavern –Work will take about 1 month –Can operate with present power-on procedure while working on enhancements

6. 21-Jan-2009CSC - ESSC Jan'096 HV Replace faulty resistors in HV system –Work started at ISR –Work will take ~2 technicians ~2 months –Working serially > most of CSC can have HV ON during work Investigate losses of communication between HV system and PVSS –HV computers located in S1A10 …

7. 21-Jan-2009CSC - ESSC Jan'097 FE Reduce rate of CRC errors in DAQ system –Rare but disruptive of Global DAQ Develop a loopback test between the TMB and ALCT to allow the testing of the skew-clear cables between the chambers and peripheral crates. –Present methods are not effective in timing in a small percentage of chamber electronics –Developing a more rigorous testing procedure to bring the lost communication rate down Further analyze the loss of programming of EPROMs in on-chamber electronics boards –Believed to be partially caused by power-on sequence > see previous slide –Have isolated problem boards for investigation on the bench –Have instituted work around to automatically identify problem situations and rapidly respond with operator intervention
