NAME

Lab::Moose::Instrument::OI_Triton - Oxford Instruments Triton gas handling system control

VERSION

version 3.822

SYNOPSIS

use Lab::Moose;

my $oi_triton = instrument(
    type => 'OI_Triton',
    connection_type => 'Socket',
    connection_options => {host => 'triton'},
    max_temperature => 1.1, # Maximum temperature setpoint.
                            # Defaults to 0.7 K.
);

my $temp = $oi_triton->get_T();

METHODS

get_temperature

$temp = $oi_triton->get_temperature(channel => 1);

Read out the current temperature of a resistance thermometer channel configured in the Triton software. This does not trigger a measurement but merely returns the last measured value. Measurements progress as configured in the Triton control panel and the resistance bridge.

get_temperature_resistance

$resistance = $oi_triton->get_temperature_resistance(channel => 1);

Read out the current resistance of a resistance thermometer channel configured in the Triton software. This does not trigger a measurement but merely returns the last measured value. Measurements progress as configured in the Triton control panel and the resistance bridge.

get_T

$oi_triton->get_temperature(channel => 5);

This is a shortcut for reading out temperature channel 5, typically the mixing chamber temperature.

set_user

$oi_triton->set_user(value => 'NORM');
$oi_triton->set_user(value => 'GUEST');

Set the access level as configured in the Triton software. Typically, GUEST means read-only access and NORM means control access.

enable_control/disable_control

$oi_triton->enable_control();
$oi_triton->disable_control();

Equivalent to

$oi_triton->set_user(value => 'NORM');
$oi_triton->set_user(value => 'GUEST');

respectively.

set_temp_pid/get_temp_pid/enable_temp_pid/disable_temp_pid

$oi_triton->set_temp_pid(value => 'ON');
# or equivalently $oi_triton->enable_temp_pid();

$oi_triton->set_temp_pid(value => 'OFF');
# or equivalently $oi_triton->disable_temp_pid();

Set PID control of the mixing chamber temperature to 'ON' or 'OFF'.

set_temp_ramp_status/get_temp_ramp_status

$oi_triton->set_temp_ramp_status(value => 'ON');
$oi_triton->set_temp_ramp_status(value => 'OFF'); 

my $status = $oi_triton->get_temp_ramp_status();

Control and read out whether the temperature is being ramped.

set_temp_ramp_rate/get_temp_ramp_rate

$oi_triton->set_temp_ramp_rate(value => 1e-3); # 1mk/min
my $ramp_rate = $oi_triton->get_temp_ramp_rate();

Set and read out the temperature ramp rate in K/min.

get_max_current

$current_range = $oi_triton->get_max_current();

Return the mixing chamber heater current range (in Amperes).

set_max_current

$oi_triton->set_max_current(value => 0.005);

Set the mixing chamber heater current range (in Amperes).

set_T

$oi_triton->set_T(value => 0.1);

Program the GHS to regulate the temperature towards a specific value (in K). The function returns immediately; this means that the target temperature most likely has not been reached yet.

get_P/set_P

my $power = $oi_triton->get_P();
$oi_triton->set_P(value => $power);

Get/set the mixing chamber heater power (in micro Watts).

Obviously this only makes sense while we're not in loop control mode.
