class dodal.devices.insertion_device.AppleKnotController

Controller for Apple Knot undulator with unique feature of calculating a move path through gap and phase space avoiding the exclusion zone around 0-0 gap-phase. See https://confluence.diamond.ac.uk/x/vQENAg for more details.

Parameters:

• apple (Apple2[TypeVar(PhaseAxesType, bound= UndulatorLockedPhaseAxes)])

• gap_energy_motor_converter (EnergyMotorConvertor)

• phase_energy_motor_converter (EnergyMotorConvertor)

• path_finder (AppleKnotPathFinder)

• maximum_gap_motor_position (float, default: 100.0)

• maximum_phase_motor_position (float, default: 70.0)

• units (str, default: 'eV')

• name (str, default: '')

Methods

check_top_bottom_phase_match()

Check that the top and bottom phase motors are in sync.

Attributes

async check_top_bottom_phase_match() → None

Check that the top and bottom phase motors are in sync. Raise an error if they are not within tolerance.

Return type:

None
