You will likely want the reference laser
- make sure space is clear
- Rayonix is all the way back
- Rayonix has the cover plate on it
- tubing and cabling are properly cinched to beampipes
- no people
- bring detector into safe X and Z above the chamber; slowly and manually, so the only motion left to do will be down in Y with a cleared path.
- DO NOT GO TO A SAVED POSITION FROM HERE AS WE'RE NOT SURE THE PATH IT MIGHT TAKE
- bring down in Y
- rotate about Y (yaw) to remove the cover plate
- DO NOT INSERT DETECTOR TUBE YET
- rotate back to about parallel to the faceplate
- place a spirit level on top of the small flat surface on top the detector
- optimize the rotation about Z (roll), and rotation about X (pitch)
- remove spirit level
- place a piece of fluorescent tape behind the detector
- ideally the Rayonix is there, with cover plate, so add the tape to the plate centered about the reference laser
- with reference laser on ideally (can be done with X-rays but why be so dangerous) optimize the X and Y position
- then adjust the rotation about Y (yaw)
- then insert the detector tube and optimize again with the smaller hole.
- SAVE THIS POSITION ON THE PENDANT
- slow the speed down and move the detector in -Z
- SLOW IT ODWN FURTHER
- and find the closest support BE AWARE that the faceplate and the detector face might not be perfectly parallel, so look closely for collisions away from you
- SAVE THAT POSITION and perhaps note it as closest approach
- with X-rays on do the same tuning in REMOTE MODE (typically just X and Y positions but maybe Yaw again)
- If the detector tube is close enough to the interaction region you can see it on the on-axis camera, visually center it about your crosshairs and then tune is with the x-ray scatter on the detector face
Turning on detector
Make sure chiller is on.
