dodal.devices.electron_analyser.base.ElectronAnalyserController#

class dodal.devices.electron_analyser.base.ElectronAnalyserController[source]#

Specialised controller for the electron analysers to provide additional setup logic such as selecting the energy source to use from requested region and giving the driver the correct region parameters.

Parameters:

  • driver (TypeVar(TAbstractAnalyserDriverIO, bound= AbstractAnalyserDriverIO))

  • energy_source (AbstractEnergySource)

  • shutter (FastShutter | None, default: None)

  • source_selector (SourceSelector | None, default: None)

  • deadtime (float, default: 0)

  • image_mode (ADImageMode, default: <ADImageMode.SINGLE: 'Single'>)

  • driver – The electron analyser driver to wrap around that holds the PV’s.

  • energy_source – Device that holds the excitation energy and ability to switch between sources.

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

  • image_mode – The image mode to configure the driver with before measuring.

  • shutter

  • source_selector
