1 1 L1CAL for DAQ Shifter By Selcuk Cihangir 3/20/2007 Representing L1CAL group (slides from many people)

2 2 Outline Why? What? When and where? (Obvious) How? What to do with it? (Procedures) Last Word, until……

3 3 Why? Obsolete components of old system (1988) Operate with 132 ns and 396 ns bunch spacing at L=2x10 32 Improved sampling and filtering to more precise measurement of Et on trigger towers, better threshold and better background rejection Additional rejection from cal-track matching Able to do clustering, finding objects (electron, jets, taus, etc): Used to be done at L2 for RunIIa More compact system, easy maintenance

10 10 Experts Do Download Firmware Initialize the system Do pedestal runs (not anymore) Adjust Pedestals Power up and down the system Do Pulser Runs Others What does the shifter do?

11 11 L1Cal Expert Programs L1Cal TCC COOR Monitoring Clients Bit3 Ethernet TFW SCL Procedures-Monitoring Tools (for Experts) L1Cal TCC GUI

12 12 New Tool: Adjust Pedestals (for Experts) Possibility to return the previous values Records of changes are kept Click to run. Takes a minute Get to this from Control/Status Button of the L1Cal TCC GUI

13 13 L1Cal Expert Programs L1Cal TCC COOR Monitoring Clients Bit3 Ethernet TFW SCL L1Cal TT Monitor GUI Menu: Take Mean Meanx100 SDx100 Operation Condition BX Choice Max ADC   Detector Region One turn of data every 5 seconds

15 15 Record TT’s beyond range Best Indicator to problem TT: Large SD

16 16 Record TT’s outside range Chose E or Et Logfile_2007_03_10_14_17_39 In directory this is run from New Tool: Recording problems (for Experts)

17 17 HAD TT (-9,22) Catching a Hot TT Information from Recorded monitoring GUI

18 18 L1Cal Expert Programs L1Cal TCC COOR Monitoring Clients Bit3 Ethernet TFW SCL L1Cal TAB/GAB Status GUI Displays the ERROR codes at TABs and GAB as they occur

19 19 New Tool-Coming Soon should always be running without any human intervention as long as one of several online host is available. -> checks the full digital chain of the L1Cal: -> parity, sync and BC errors for digital transmission in ADF->TAB->GAB -> parity of TAB/GAB -> L2/L3 data -> BC synchronization between ADF/TAB/GAB and VRBs. -> Bitwise agreement of simulated and/or terms from measured raw TTs.

20 20 New Tool-Cont. This requires some judgment from the shifter. If it's the start of a new store or new run, or between stores and the L1Cal is out of the crate, then it might be stalled for up to a few minutes. Problem detected, page L1Cal

21 21 L1Cal Expert Programs L1Cal TCC COOR Monitoring Clients Bit3 Ethernet TFW SCL Tower Exclusion Online Examine Pulser Run Pedestal Calibration Gain Calibration More Procedures (for Experts)

22 22 Online Examine Warm TT’s Confirm with Monitoring GUI SD display Hot Cal Tower? Adjustable threshold

23 23 Different threshold Dead Towers? Online Examine

24 24 Last Word…. A versatile system Still improving We are learning more about its capabilities Developing new tools as needs arise Until …… We re-write this presentation once we know more…………
