magnetlogger

Log status of Janis cryostat and Cryomech reliquifier.

DESCRIPTION

This toolbox reads information on a Janis Research Co. Model
7THL-SOM2-11 Split Superconducting Magnet system and a Cryomech PT410
reliquifier. It stores a variety of information: pressure, temperature,
heater value, helium level, compressor status, etc. and checks whether
these values fall within a desired range. If an error is detected then
an email is sent to the group.
This package is realtively specific to the Kai-Mei Fu lab at University
of Washington. However, with some knowledge of matlab, it can be
modified to suit other systems.

FUNCTIONS

MAGNETLOGGER - GUI for logging magnet information
WRITEMAGNETLOGENTRY - Writes one log entry to the magnetlog
CRYOSTATPRESSURE - read pressure from analog in
GETCURRENTMAGNETLOGFILENAME - get filename and path for today's log entry
GETLASTMAGNETLOGENTRY - return last magnet log entry
MAGNETLOGERRORCHECK - check for cryostat issues
MAGNETLOGGERFIGURE - draw figure for magnetLogger

INSTALL

A small number of changes are necessary to get the magnetLogger working
on your computer. You may also need to modify some of the scripts to
suit the purposes of your lab.

1. In send_mail_message, enter your email address and password.

2. In getCurrentMagnetLogFileName, enter the directory where the magnet
log files will be saved.

3. Enter the email addresses where error messages will be sent in
