device.trap_cathode module

class device.trap_cathode.TrapCathodeHeater(calibfile, bus, limits_enabled=True, **kwargs)

Bases: ArduinoMotorsBase

Arduino based motor controller (trap experiment), which controls the autotransformator output. Also there are two power relays.

Communication:

• serial interface to Arduino

current()

Return the current in cathode

homing()

Execute homing procedure for each of the motors.

is_output_on()

Return the state of relay that powers transformator.

moveto(position)

Move motor to position [mm].

set_current(current)

Set output transformator current [A] by moving the motor.

switch_output_off()

switch_output_on()
