Lab::Moose::Instrument::Lakeshore340::Helium3 - Lakeshore Model 340 Temperature Controller for Helium3 operation
version 3.831
use Lab::Moose; # Constructor my $helium3 = instrument( type => 'Lakeshore340::Helium3', connection_type => 'LinuxGPIB', connection_options => {pad => 22}, );
default thermometers: sample => 'A' sample_high => 'B' (optional) sorb => 'C' 1K-pot => 'D'
Can be configured with attributes sample_channel, sorb_channel, one_K_channel.
sample_channel
sorb_channel
one_K_channel
default heater config: loop 1 (dual Banana jack) => sorb heater loop 2 (Analog output 2, BNC) => he3-pot heater
(Analog out 1 can be used for IVC-sorb)
The attribute T_switch (default: 1.5) determines the used control loop for a given temperature setpoint:
T_switch
- T < T_switch: use sorb heater, ramp sample heater to zero - T > T_switch: use 3He-pot heater, set sorb to 15K
Supports all methods from Lab::Moose::Instrument::Lakeshore340.
$lakeshore->condensate( T_sorb => 35, # default: 35 K wait => 1800, # default: 30 min T_cool => 0.4, # default: 0.4 K );
Heat sorb to 35K for 30min. Then turn off sorb heater and wait until sample temperature is below 400mK.
$helium3->set_T(value => 0.345);
Behaviour depends on the attribute value T_switch (see "Synopsis").
