| USHM | XPS:LI20:MC03 | PB10 M2 Removal Stage | MC03, M1 | OAPs in:
laser vector alignment: 0.5 (cross-check with 305 value above) | E-320 position: mirror on the right side of the e-beam, steering laser onto 1st OAP | April 30, 2024 |
Alignment Target Vertical UP/DOWN | XPS:LI20:MC10 | PB11 SFQED Target Vertical | MC10, M1 | 0-9048.35 | highest position / lowest position / out position when OAP is IN / YAG in position ATTENTION: collisions possible, follow exact procedure, check target position before moving OAPs / MO tower DON'T GO LARGER THAN 90 EVER http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2024/17/24.04&pos=2024-04-24T23:48:34 | April 24, 2024 |

| December 14, 2022 |
| OAP Assembly IN/OUT | XPS:LI20:MC10 | PB16 SFQED Assembly Removal | MC10, | 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 | April 30, 2024 | |
| Elliptical mirror/M3 IN/OUT | XPS:LI20:MC10 | PB17 Elliptical mirror mover | MC10, M4 | Positive limit switch/negative limit switch + 7 | 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 Vertical | XPS:LI20:MC10 | PB18 Focus Imaging Vertical | MC10, M5 | 0.427 | Home at current position (0). Motor should not be touched or moved, should be clear in any case. | |

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 90
- 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.
