device.trap_diganostics module

class device.trap_diganostics.TrapDiagnostics(bus, bus_switch, **kwargs)

Bases: ArduinoBase

Multi-purpuse Arduino controller that handles

• 16x DS18B20 digital thermometers, one for each coil

• 1x thermocouple, measures temp of the heated cathode insulation

• 1x Hall probe

• 1x needle valve

Communication:

• serial interface to Arduino

close_needle()

Close the needle valve, shorthand for set_needle(0).

get_needle()

Get current state of the needle valve 0-100%.

is_main_on()

main_switch_off()

main_switch_on()

measure_field()

Measure magnetic field using the Hall probe.

set_needle(percent)

Set state of the needle valve 0-100%.

Parameters:

percent (float) – Percentage in range 0-100, where 0 is closed.

set_needle_for(percent, duration)

Set state of the needle valve 0-100%, close it when duration is exceeded.

Parameters:

• percent (float) – Percentage in range 0-100, where 0 is closed.

• duration (float) – Time interval in seconds.

temp_cathode()

Read temperature of heated cathode insulation.

temp_coils()

Read temperature of all 16 coils.
