This page describes, or has links to descriptions of, all scripts used at the 40m.

• Find the Locking Scripts here.

Scripts that run all the time (usually):

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.

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.

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.

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.
