XPS:LI20:MC10PB11 SFQED Target VerticalM10/99

Home position, needed when inserting or retracting OAP assembly. Do not drive to home (0) when MO tower is in IN position.

/Clear position with and without OAP assembly. Moving assembly requires moving out of clear position.

MO Tower Mover IN/OUTXPS:LI20:MC10PB12 SFQED Tower MoverM2-94.83/0

IN position to look at focal spot.


Clear (retracted), also home position, needs to be done before retracting SFQED assembly

OAP Assembly IN/OUTXPS:LI20:MC10PB16 SFQED Assembly RemovalM3114/0

IN position to focus main beam.

Clear (retracted), also home positions, needs MO Tower to move out first, also needs Alignment target to move upwards first

Elliptical mirror/M3 IN/OUTXPS:LI20:MC10PB17 Elliptical mirror moverM4Positive limit switch/negative limit switch + 12

Out position. Configuration is 'SetCurrentPositionAsHome',so need to drive all the way to positive limit switch to ensure driven out.

In position. Drive all the way to negative end for IN position.

PB18 Focus Imaging VerticalXPS:LI20:MC10PB18 Focus Imaging VerticalM50Home at current position (0). Motor should not be touched or moved, should be clear in any case.

Safely retracting E320 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.
