dodal.devices.undulator.Undulator

class dodal.devices.undulator.Undulator

An Undulator-type insertion device, used to control photon emission at a given beam energy.

Parameters:

• prefix (str)

• id_gap_lookup_table_path (str, default: '/dev/null')

• name (str, default: '')

• poles (int | None, default: None)

• length (float | None, default: None)

Constructor

Parameters:

• prefix (str) – PV prefix

• poles (int) – Number of magnetic poles built into the undulator
