====== CMS BPIX Detector Commissioning at P5======

===== Schedule ===== 
Doodle calendar: http://doodle.com/poll/ute3fhk3epepd4aw

===== Testing procedure =====

  - Login to DCS
      * Account: CERN\tkdcsmt, pw: Meri-Wuwi (in case someone is logged in from remote call Stefanos 1820 or Christian 0897)
      * If the DCS is not already running, click on icon P5-BPIX.bat on the Desktop
      * Click on Cooling: Verify that all temperatures are as expected (usually around 18C)
      * Go to Hardware Views --> Power supply view --> By Mainframe --> "Show the panel of this rack"
      * Power CCU (2nd module 4602, top) --> Enable --> On (expected current about 1.6A) 
      * Power Opto (1st module 4602) [LV 1,2,3,4 for S4,3,2,1 (upper cable), for S5,6,7,8 (lower cable)] --> Enable --> On (expected current about 2-3A) 
      * Power detector (1st module 4603, top SEC1 L14, bottom SEC1 L23, 2nd module 4603, top SEC2 L14, bottom SEC2 L23, 3rd module 4603, top SEC3 L14, bottom SEC3 L23, 4th module 4603, top SEC4 L14, bottom SEC4 L23) only LV for now --> On (expected current about 4A)
  - Check CCU ring and ST i2c communication using BPixelTools  (see How to run BPixelTools)
  - Start testing with POS (see How to run POS)

===== How to run BPixelTools ===== 

  source TriDAS_r45/pixel/POSRelease/setenv.sh
  cd TriDAS_r45/pixel/BPixelTools/ccu
  ./run.bsh 

  scanccu
  FEC 0x0 Ring 0x0 CCU 0x7e found
  FEC 0x0 Ring 0x0 CCU 0x7d found
  FEC 0x0 Ring 0x0 CCU 0x7c found
  FEC 0x0 Ring 0x0 CCU 0x7b found
  FEC 0x0 Ring 0x0 CCU 0x7a found
  FEC 0x0 Ring 0x0 CCU 0x79 found
  FEC 0x0 Ring 0x0 CCU 0x78 found
  FEC 0x0 Ring 0x0 CCU 0x77 found
  
  scanringedevice
  prints list of all i2c devices 
  
  ccu 0x7c (select the ccu of interest, see for instance the result of scanringedevice)
  piareset all
  reset
  qpll
  both qpll locked
  power off
  (turn on LV on DCS)
  power on

  * If you do not see the expected output, try to powercycle the CCU and opto power. 
  * If scanringedevice crashes, try to disconnect and reconnect the fibers going to the TKFEC. 
  * If the QPLL are not both locked, try "pll reset" or "piareset all" again.


===== How to run POS ===== 

  source TriDAS_r45/pixel/POSRelease/setenv.sh
  cd TriDAS_r45/pixel/PixelRun
  ./run.sh --xml auto

  go to http://cmspixel2.psi.ch:1973/
  
  click on "PixelSupervisor"
  click "Initialize"
  select calibration to run
  click "Configure"
  check that FED phases have been found
  click "Start" 
  
  Once the calibration finished. Look at the results in:
  cd TriDAS_r45/pixel/PixelRun/Runs/Run_0/Run_yourrunnr
  
  
=== How to analyze PixelAlive and SCurve === 
  
  $BUILD_HOME/pixel/PixelAnalysisTools/test/bin/linux/x86_64_slc6/PixelAnalysis.exe $BUILD_HOME/pixel/PixelAnalysisTools/test/configuration/PixelAliveAnalysis_41_43.xml yourrunnur
  
  $BUILD_HOME/pixel/PixelAnalysisTools/test/bin/linux/x86_64_slc6/PixelAnalysis.exe $BUILD_HOME/pixel/PixelAnalysisTools/test/configuration/SCurveAnalysis_41-43.xml yourrunnur
  
Edit xml file to include the FEDs of interest.  
===== List of Calibrations =====   

  TBMDelay25 --> check chose SDA value, if ok updatePortcard.
  POHBiasBPIX --> updatePortcard.
  SCurve without HV
  SCurve with HV --> run analysis, compare using script in /home/cmspixel/scurves/scurves.py
  
  In case of problems with the readout try the following sequence
  TBMPLLDelayNoTokenPass --> updateTbm 
  2DScores --> updateTbm
  TBMPLLDelay400MHz --> updateTbm
  
===== How to update TBM, ROC and portcard settings =====   
  
   - Go to the Run directory with the results of the calibration you would like to update

  cd TriDAS_r45/pixel/PixelRun/Runs/Run_0/Run_X
  ../../../updateTbm
  ../../../updateRoc
  ../../../updatePortcard
  (depending on what you would like to update)
===== How to go to the next sector ===== 
  - Connect module power and fibers
  - Change POS configuration files to appropriate sector

  cd TriDAS_r45/pixel/config
  cd detconfig/1/
  cp detectconfig.dat_sector detconfig.dat
  cd ../../nametranslation/1/
  cp translation.dat_sector translation.dat
  cd ../../portcardmap/1/
  cp portcardmap.dat_sector portcardmap.dat

===== Elog =====  

  Keep track of your results by entering them in this elog: 
  (user and password are the same as to access testing PC). 
  
https://elog.physik.uzh.ch:8080/PixelPOS/
  
  *   For each sector, write down all currents at power up and after configure.  
  *   For each calibration: enter sector, run number and calibration type and additional information if needed.
  *   For each sector, enter a summary of working/non-working components. 

===== How to login to underground PCs =====  

  Login to cmsusr:
  ssh -Y username@cmsusr
  
  From there login to any of the pixel PCs, for example:
  ssh -Y srv-s2b18-32-01 
  
  Become pixeldev:
  xsudo -u pixeldev -H bash -l
  cd ~pixeldev
  
  Go to POS installation:
  cd ~pixeldev/TriDAS_r45/pixel/PixelRun
  
  Config files are under:
  /pixel/config/BPix/
  
  Open firefox on cmsusr login node and go to PixelSupervisor:
  http://srv-s2b18-32-01.cern.ch:1973
  
  
  
===== How to power up =====  
  
  As pixeldev open three terminal windows. 
  
  Start the BPixelTools ccu program in the first tab:
  cd ~pixeldev/TriDAS_r45/pixel/BPixelTools/ccu
  ./run_bpi.bsh (or ./run_bpo.sh, ./run_bmi.sh, ./run_bmi.sh depending on the quadrant)
  
  (note if you change from the detector inner side (BpI/BmI) to the outer side (BpO/BmO) you will need to change the address of the TKFEC in the file ccu/connections.xml)
  
  Start the BPixelTools pxfec program in the second tab:
  cd ~pixeldev/TriDAS_r45/pixel/BPixelTools/pxfec
  ./run.bsh
  
  Use the third tab to run the python script:
  cd ~pixeldev/TriDAS_r45/pixel/BPixelTools/testLea
  
  For each sector you want to power on run:
  python powerOnDcdc.py sectorid
  , where sectorid is bmi1,bpi1,bmo1,bpo1,etc
  
  To power off:
  python powerOffDcdc.py sectorid
