PSLWatch

• PSLWatch is a perl script running on op340m. It watches the PSL, and dispatches the appropriate of lockMZ, lockPMC, or lockFSS. It has a blinky.

FSSSlowServo

• The FSSSS is a perl script running on op340m. It implements a PID servo that uses the PSL-FAST (the NPRO PZT control signal) as an error signal, and feeds back to PSL-SLOWDC (which changes the crystal temperature). You can manipulate the gain, settings, timeouts, etc. on the C1PSL_SLOW.adl screen. It blinks its light everytime it does something. Can be disabled with the channel C1:PSL-FSS_SLOWLOOP.

offset

• This code zeros the offset of a filter bank. The digital offset will be adjusted by  ezcaservo.

  •     Example usage : offset C1:LSC-AS55Q 

offset2

• This code zeros the offset of a filter bank. The digital offset will be adjusted based on the measurement of tdsavg,

  •     Example usage : offset2 C1:LSC-AS55Q 

RGA logger

• RGAlogger In $SCRIPTS/RGA, it polls the RGA for data and settings, and puts these into two files: RGA-date.data RGA-date.settings both in the $SCRIPTS/RGA/logs directory. It also checks the file $SCRIPTS/RGA/alarms/RGAalarms.spec for limits on certain AMUs, and compares the current data to the limits. If the current partial pressure of a given AMU exceeds its specified limit, it puts that information into a file called RGA-date.alarms. Run as a cronjob every day at 12.05 am by op340m.

autolockMCmain40m

• autolockMCmain40m is the Mode Cleaner autolocker script. It watches the mode cleaner transmitted power level, and runs the appropriate script when certain conditions are reached.

• The subscript mcup ramps gains, engages boosts, and turns on the WFS.

• mcdown is the inverse of mcup. It can be enabled or disabled by using a button on the C1IOO_LockMC.adl screen. This script runs all the time on op340m. It's written in csh, and is fairly robust. It may crash when c1psl is rebooted.

• A cron job on op340m occasionally checks whether it's running and restarts it if it isn't. Any changes to the mode cleaner states (lock acquisition or in-lock) should be made in the mcup and mcdown scripts, in the $SCRIPTS/MC/ directory. autolockMCmain40m should not be edited.

  • {{{ ssh op340m
    • cd /opt/rtcds/caltech/c1/scripts/MC

bobafett.pl

• Location: $SCRIPTS/starwars/
• Name: bobafett.pl
• Use: run without additional arguments This script can be used to manually align a component (TM or TT-PZT stage) in the PIT and YAW using the keypad on the keyboard. It does exactly what the (1D) sliders do in the EPCIS screens, but you don't have to move the mouse around when swapping axis. When started, the user will be presented with a menu with the choice of all the components of the 40m. With the Num Lock 'ON', the up(8) and down(2) arrows will move the component in positive and negative PIT respectivily. While the left(4) and right(6) will move in positive and negative YAW, respectivily. To change the step size, you use the (7) and (9) keys to increase and decrease, respectivily. The change is written directly to the '_COMM' channel of the component. When one of the PZT stages is chosen, the step size is automatically multiplied by 10k (which will be shown). The script can be ended by pressing 'q'.

blinky

• Location: $SCRIPTS/general/blinky
• Name: blinky.pl
• Use:

blinky is used to provide heart beat functions to scripts (e.g. PSLwatch and mcautolock40m) when that script dies, this one dies too.

usage: blinky <channel name> usage: blinky <channel name> <optional blink rate> usage: blinky <channel name> <required blink rate> <parent perl script pid>option 3 is for calling this function inside a perl script where the

• grandparent pid is needed. default blink rate is 1 pulse per seconds

Run on OP340m.

E.g. if the MC autolocker is not blinking log into OP340m, find the PID of autolockMCmain40m (1234, say) and type 'blinky C1:IOO-MC_AUTOLOCK_BEAT 1 1234 &'

Cron jobs

You are encouraged to make a copy of crontab files in /cvs/cds/caltech/crontab/ whenever you edit a crontab on a machine after confirming it works fine. This directory is svn managed. So do svn ci after you update a file.

nodus

The current crontab of controls@nodus is the following:

• 0 10 * * * /cvs/cds/caltech/scripts/backup/check_backup.sh 0,5,10,15,20,25,30,35,40,45,55 * * * * /cvs/cds/caltech/statScreen/bin/cronjob.sh 2,12,22,32,42,52 * * * * /cvs/cds/caltech/scripts/webStatus/webStatus.sh 

• check_backup.sh will check the daily backup status.

mafalda

attachment:mafalda_s.jpg

• statScreen/bin/cronjob.sh will take screen shots of MEDM screens and post it on the web.

• webStatus.sh uses tdsread to get a bunch of EPICS values and post them on some web page.

armLoss

• This code measures the visibility at ASDC while continuously lock and unlock an arm. Hence it allows us to measure the arm loss.
• The measurements will take place forever, so one has to force-quit the command at some point.
• The measured values will be acquired in a text file in the same directly and the file name will be loss-Y-XXXXX.log, where XXXXX is the time when the measurement starts.

  •     Example usage : armLoss
       (to stop the measurement) Ctrl-C 

LSCoffsets

• This code zeros all the LSC offsets. First this code will shut out the PSL mechanical shutter so that no lights go into any PDs.
• Then it runs ezcaservos for all the LSC PDs (e.g. AS55, REFL11 and so on) and all the DC PDs (e.g. ASDC, REFLDC,..) to cancel the electrical offsets by adjusting the digital offsets.

  •     Example usage : LSCoffsets 

orthogonality.py

• This script will measure the orthogonality of a set of I and Q signal.

  •      Example usage : orthogonality.py -c REFL11
         help : orthogonality.py -h

Anchor(assUpX(Y)arm)

assUpX(Y)arm

medmrun

• This script is a wrapper for running scripts from medm in an xterm. It expects at least one argument, which is the script to run. A second argument, if provided, is the xterm title. If not provided, the title of the xterm will be the name of the script.
  • {{{ example usage :
  • medmrun assUpYarm

}}}

setTRAMP

• This script will set all the TRAMP values to a specific value in a model. The TRAMP time can be specified as an argument of the script.
  • {{{ example usage : setTRAMP LSC 1

}}}

opticshutdown

• This script, written in bash, shutdowns all the suspensions at once and keeps it for 5 hrs. After the 5 hrs then this script brings the suspensions back to normal. It is useful when you want to diagnose the suspensions.

  •   /cvs/cds/rtcds/caltech/c1/scripts/SUS/opticshutdown 

freeswing

• This code gives a kick on an optic of interest and leaves it free swing forever. Unlike [#opticshudown opticshutdown], this code doesn't automatically return the watchgods on. So one should turn the watchdogs on after the measurement/diagnosis.

  • example 1:
      freeswing ITMY    (let ITMY free swing)
    example 2:
      freeswing         (let ALL of the optics free swing)

F2P_LOCKIN.py

• This script measures the f2p ratio on an optics of interest

  •    Example usage : F2P_LOCKIN.py -o ITMY
       Display help : F2P_LOCKIN.py -h 

videoswitch

• This scripts switches the video matrix

  •    Example usage : videoswitch.py Mon2 REFL
       Display help : videoswitch.py -h 

daqconfig

• Configures the DAQ channels

  •      Example usage : daqconfig 

activateDQ.py

• Activates the necessary DQ channels on the SUS machine.

  •         Example usage : activatedDQ.py

pynds_40mtest.py

• a demo for pynds

  •      Example usage : pynds_40mtest.py 

killdataviewer

• kills dataviewer processes

pmath

• This perl code does simple calculations.

  • {{{ usage: pmath <expr> Example 1: pmath '2 * 3' Example 2: set goo = pmath '2 < 3'

}}}
