Lab::Instrument::OI_Mercury::Magnet - Oxford Instruments Mercury Cryocontrol magnet power supply
use Lab::Instrument::OI_Mercury::Magnet; my $m=new Lab::Instrument::OI_Mercury( connection_type=>'Socket', remote_port=>7020, remote_addr=>22.214.171.124, blabla .... );
The Lab::Instrument::OI_Mercury::Magnet class implements an interface to the Oxford Instruments Mercury magnet power supply units.
The Mercury uses a command language that looks a bit like SCPI but is actually incompatible with that specification.
Read out the designated temperature channel. Result is in Kelvin.
$mcat=$m->get_catalogue(); print "$mcat\n";
Returns the hardware configuration of the Mercury system. A typical response would be
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.
Reads out the momentary current of the PSU in Ampere. Only Z for now.
TODO: what happens if we're in persistent mode?
Returns the persistent mode switch heater status as "ON" or "OFF".
Switches the persistent mode switch heater. Parameter is "ON" or "OFF". Nothing happens if the power supply thinks the magnet current and the lead current are different.
Switches the persistent mode switch heater. Parameter is "ON" or "OFF".
Dangerous. Works also if magnet and lead current are differing.
Gets the current target sweep rate (i.e., the sweep rate with which we want to go to the target; may be bigger than the actual rate if it is hardware limited), in Ampere per minute.
Sets the desired target sweep rate, parameter is in Amperes per minute.
Sets the current activity of the power supply. Values are:
HOLD - hold current RTOS - ramp to set point RTOZ - ramp to zero CLMP - clamp output if current is zero
Retrieves the current power supply activity. See oim_set_activity for values.
Sets the current set point in Ampere.
Returns the current to field factor (A/T)
