[Relm-Arrowny]

Goals

Acceptance criteria :

• To be able to control pgm and apple2 devices via set.
• To be able to read and set polarisation.
• To perform energy scan with both pgm and insertion devices.
• A set of dodal devices are needed that acheve the goal.

Tasks

base on the goals, deduce the tasks required. check them off once they're done

• Create apple2 device.
• Create an energy to motor (ETM) position function.
• Use the apple2 and the ETM function to make a apple2 controller that control energy and polarisation.
• Using the controller to make a id energy and polarisation device.
• Combine the id energy and PGM to from beam energy device to control the beamline energy.
• Add all these device to beamline config.
• i-21 change their grating at different energy. So look up table needed to pick up the grating column.
• Beamline energy set need to now change PGM grating as well as closing the FE during energy change.
