Alignment
Timeline
| Completion Date | Task |
| 4/29/11 | remove HRRL Gun |
| 5/2/2011 | Install alignment laser( Khalid's 2'x3' table in HRRL doorway) |
| 5/3/2011 | Install rotation and translation stages |
| 5/9/2011 | Align zero degree beam line |
| 5/12/2011 | Align 45 degree beam line |
| 5/13/2011 | Align 90 degree beam line |
Procedure
2 translators, one at least X feet. The long one is on the bottom and used to move a mirror from the zero port along the beamline to the expeimental celll. The second one is short and mounted on top of the long one. This will move along the HRRL axis
- Align laser through HRRL entrance and exit.
- place tanslators
- move translator along HRRL direction and position until laser spot doesn't move out of two Iris's at limits of translator breadboard.
- Not you are aligned along the HRRL axis
- Place mirror on translator and be sure laser beam goes back to HRRL gun.
- Rotate stage 45 degrees
- Move along translator to center laser as much as possible through the experimental cell wall.
- Move the alignment laser to the experimental side and shoot beck to HRRl side
- Move the 45 degree mirror to the location of D2
- Install a 45 degree mirror at D1's location
- Be sure the laser shines back to the cent of the Gun location
Should we increase the dipole gap? From 3/4" to what?
