Safely retracting E-320 assembly and setting up to clear e-beam/laser will be:
- Drive PB12 SFQED Tower Mover to 0 (home)
- Drive PB11 SFQED Target Vertical to 0 (home)
- Drive PB16 SFQED Assembly Removal to 0 (home)
- Drive PB11 SFQED Target Vertical to 99
- Drive PB17 Elliptical mirror mover to most positive end
Note: TRA motors on MC10 currently do not work in EPICS (position is shown correctly). Drive through XPS web interface.
