NAME

Lab::Instrument::OI_Mercury - Oxford Instruments Mercury Cryocontrol

SYNOPSIS

use Lab::Instrument::OI_Mercury;

my $m=new Lab::Instrument::OI_Mercury(
  connection_type=>'Socket', 
  remote_port=>7020, 
  remote_addr=>1.2.3.4,
);

DESCRIPTION

The Lab::Instrument::OI_Mercury class implements an interface to the Oxford Instruments Mercury cryostat control system.

METHODS

get_catalogue

$mcat=$m->get_catalogue();
print "$mcat\n";

Returns the hardware configuration of the Mercury system. A typical response would be

STAT:SYS:CAT:DEV:GRPX:PSU:DEV:MB1.T1:TEMP:DEV:GRPY:PSU:DEV:GRPZ:PSU:DEV:PSU.M1:PSU:DEV:PSU.M2:PSU:DEV:GRPN:PSU:DEV:DB5.L1:LVL

Here, each group starting with "DEV:" describes one hardware component. In this case, we obtain for example:

DEV:GRPX:PSU     |
DEV:GRPY:PSU     |- a 3-axis magnet power supply unit
DEV:GRPZ:PSU     |
DEV:MB1.T1:TEMP  -- a temperature sensor
DEV:DB5.L1:LVL   -- a cryogen level sensor

In each of these blocks, the second component after "DEV:" is the UID of the device; it can be used in other commands such as get_level to address it.

get_temperature

$t=$m->get_temperature('MB1.T1');

Read out the designated temperature channel. Result is in Kelvin (?).

get_he_level

$he=$m->get_he_level('DB5.L1');

Read out the designated liquid helium level meter channel. Result is in percent as calibrated.

CAVEATS/BUGS

probably many
