Subject: keyed psl crate, unstick.py 

Mode cleaner was not locked today. Koji came in and concluded that PSL had died. So we keyed it. Then we ran my unstick.py code. Mode cleaner is locked now.

Quote:

Today, Gautam keyed the C1PSL crate and we got to test my unstick.py code. It seems to be working fine. Remarks:

  1. Gautam moved the unstick.py code to /opt/rtcds/caltech/c1/scripts/cds. Therefore, the steps to run this code are now:
    1. cd /opt/rtcds/caltech/c1/scripts/cds
    2. python unstick.py c1psl (for the c1psl machine)
  2. There is now a sleepTime global variable in the code which defines the amount of delay between successive channel toggles. We set this to 1ms and it took the code around 3s to run.
  3. Gautam was curious to see if this would work even if we set the sleepTime parameter to 0 but decided that that could be tested the next time something was keyed.
  4. I still need to add the signal handling thing to this code.

Following this, we tested my PMC autolocker code. The code ran for about a minute before achieveing lock. Remarks:

  1. Gautam moved my code (pmc_autolocker.py and autolocker_config.yaml) to /cvs/cds/rtcds/caltech/c1/scripts/PSL/PMC/ . Therefore, the steps to run this code are now:
    1. cd /cvs/cds/rtcds/caltech/c1/scripts/PSL/PMC/
    2. python pmc_autolocker.py (check code or use --help to see what the command line arguments do which is only for when you wanna override the details in the .yaml file)
  2. Gautam suggested that I add some delay between succesive steps of DC output adjust so that it locks quickly. I'll do that ASAP. For now, it works.
