December 3rd, 2018 Testers: Cameron

Goals

  • Figure out HV maps in Counting DAQ guis
  • Use monitorGui to test ET deadtime
  • Incorporate the helicity sequence monitor into simple deadtime analyzer

HV Maps

See relevant halog entry

ET Deadtime with monitorGui

  • Run 4696 - trying to get CODA working - failed
  • Run 4697 - coda works - 30 Hz injector qrt helicity information, scalers are still plugged in from prior testing
    • ET Client deadtime checker (~/et-12.0/src/cameronc/) shows 40% deadtime, and because the helicity (MPS signal) is at 50 Hz sometimes!
    • This was in blocking mode
  • Run 4698 - again, but in non-blocking mode
    • Same 40% deadtime!
  • Run 4699 - messed with the MPS cable and checked on a scope - yup 30Hz
    • After messing with the signals the deadtime is happily at 0% for non-blocking mode
  • Run 4700 - long run in blocking mode
    • No deadtime now too
    • I don't get it, and I need to open the monitorGui to see what is going on

None of these runs had any helicity errors in Japan (~/ciprian/japan/cam_build/qwparity --config prexCH.conf -r 4700) or in Bob's helicity sequence checker (~/et-12.0/src/cameronc/chkdtime /adaq2/data1/apar/parity18_4700.dat), and I looked at the BPM (pedestals, since no beam) and nothing looked horribly wrong there

Monitor Gui

I tried to open the monitorGui per Carl Timmer's instructions, but I am getting problems

setenv JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/
cd /adaqfs/home/apar/et-12.0/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre/bin/java -cp jars/jlayout30.jar:jars/jlm20.jar:jars/jloox20.jar org/jlab/coda/et/monitorGui/Monitor

Returns error:

Error: Could not find or load main class org.jlab.coda.et.monitorGui.Monitor
  • Even though that file definitely exists
  • Probably the java code needs to be compiled first, but javac is not installed, even in those proprietary jdk installs noted above

Results

The HV maps system is pretty clear

monitorGui needs some compilation or some other detailed apar@adaq3 specific help

To Do

  • Ask Carl Timmer to help run monitorGui on apar@adaq3
