API#

class ophyd_async.fastcs.eiger.EigerDetector(prefix: str, path_provider: PathProvider, drv_suffix='-EA-EIGER-01:', hdf_suffix='-EA-EIGER-01:OD:', odin_nodes: int = 4, name='')[source]#

Bases: ophyd_async.core.StandardDetector

Ophyd-async implementation of an Eiger Detector.

async prepare(value: TriggerInfo) → None[source]#

Arm detector.

Prepare the detector with trigger information. This is determined at and passed in from the plan level.

Parameters:: value – TriggerInfo describing how to trigger the detector

class ophyd_async.fastcs.eiger.EigerController(driver: EigerDriverIO)[source]#

Bases: ophyd_async.core.DetectorController

Detector logic for arming and disarming the detector.

get_deadtime(exposure: float | None) → float[source]#

Get state-independent deadtime.

For a given exposure, what is the safest minimum time between exposures that can be determined without reading signals.

async set_energy(energy: float, tolerance: float = 0.1)[source]#: Set photon energy.

async prepare(trigger_info: TriggerInfo)[source]#

Do all necessary steps to prepare the detector for triggers.

Parameters:: trigger_info – The sort of triggers to expect.

async arm()[source]#: Arm the detector.

async wait_for_idle()[source]#: Wait on the internal _arm_status and wait for it to get disarmed/idle.

async disarm()[source]#: Disarm the detector, return detector to an idle state.

class ophyd_async.fastcs.eiger.EigerDriverIO(uri: str, name: str = '')[source]#
