Set-up

See here for hardware set-up: RCESetUp

Running the RCE software

Make sure to have set-up symbolic link to RCE area, i.e. ln -s /afs/phas.gla.ac.uk/group/atlas/rcepixel01/ibldaq/IBLDAQ-0-0-0 daq

• Navigate to the directory ~/daq/rce
  • $ cd daq/rce
• Open C shell
  • $ tcsh
• Run set-up script
  • $ source scripts/setup_rce-04-00-01.csh
• Start servers
  • $ ipc_server &
  • $ rce_ipc_server &
  • $ rce_is_server &
• You can check that the servers are running using the command
  • $ rce_ipc_ls
• Load RCE (RCE ip address is 10.129.3.11)
  • $ rce_load 10.129.3.11
• Open GUI
  • $ calibGui

RCE calibGui

CalibGui is the software used to perform tunes, run scans and test devices.

Before running a scan

Once GUI is open…

• In "Scan" tab
  • Set directory to save root files by clicking "Browse" button adjacent to "Data Dir" in "Global Module Configuration area", e.g. /afs/phas.gla.ac.uk/data/atlas/upgrade01/rce-tests/
  • Select Scan Type of scan from drop down list in "Scan Config" area
  • If required choose a Prim list by "Load Primlist" button in Prim List area
    • NB prim lists have priority over any selected scan. Also, prim lists must be cleared before loading a new list or running single scan.

• In "Config Halfstave" tab (4 provided, choose whichever is appropriate)
  • Choose a "Frontend: are and set parameters for communication with chip
  • Select config file from "Choose Config", and browse to file, e.g. /afs/phas.gla.ac.uk/data/atlas/upgrade01/rce-tests/KateRCE/THRESHOLDX/config
    • NB check references to masked directories in config file are to correct place (i.e. current directories)
    • for valid config rations the "Valid" check will be ticked
  • Set inlink/outlink to valid parameters, and correct RCE (see map ADD LINK LATER)
  • make sure the "Included" check is ticked, else the communication will not be attempted

• In "Plots" tab
  • The output of them most recent scan is viewable in GUI
    • Usual root rules apply, i.e. zoom, right-click, etc.

Running a scan

Basic checks

• Is the chip powered?
• Is the chip biased (do you want it biased?)?
• Is the chip connected?

Select Scan/Primlist

View scan results in the "Plots" tab

Test/Scan Data

• Occupancy plots and histograms can be viewed in the plots tab of the calibGui.

• Data is saved in ~/calibData directory.

• There are root scripts in the ~/root_scripts directory for plotting and analysing analog, digital and threshold scan data.

• To run the analysis ROOT script open file run_analysis.C in an editor (emacs, geany). Change the run number for the Analogue, Digital & Threshold Tests on lines 5 to 7. Open ROOT in the calibData folder and run the run_analysis.C script.

IV Scan

• There is a c++ script for running an IV scan on the pixel detector using a Keithley 2410. The script is located in ~/Projects/IVProgram
• To compile and link the IV scan script do:
  • sudo g++ -m32 main.cpp -o iv_scan /usr/local/natinst/ni4882/lib/cib.o -ldl
  • To run iv_scan do:
    • cd ~/projects/IVProgram
    • ./iv_scan
