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

Scripts that run all the time (usually):

Name of script	Computer where it lives	What it does	Notes
[#PSLWatch PSLWatch]	op340m	Runs lockFSS, lockMZ, lockPMC when appropriate
[#autolockMCmain40m autolockMCmain40m]	op340m	watches the MC. Runs mcup and mcdown
[#FSSSlowServo FSSSlowServo]	op340m	Watches C1:PSL-FAST_MON and servos C1:PSL-SLOW_DC
blinky	op340m	blinks a light if a script is alive	forked by mother script
[#RGAlogger RGAlogger]	op340m	gets data from RGA nightly	Runs as a cron job
autoburt	op340m	backs up EPICS control settings hourly	Runs as a cron job

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.

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.

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 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.

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'.
