Pol He-3 Rotation Stages
The camera snapshots are to roughly verify that the rotation stages are where we think they are. This is done by looking at the relative location of the marks outlined in red. One mark is on the rotating portion, the second on a fixed part of the rotation stage.
Rotation Stage Controls
- Bring up the rotation stage controls:
go_polhe3_rotation-stage
- Camera image
- NOTE: if the screen is blue then you must turn ON the camera + lamp: Pol_He-3_Rotation_Stages#Power_to_camera_and_lamp_in_Optics_Box
Camera (Counting House Only) : Rotation Stage Camera
Power to camera and lamp in Optics Box
- Use Outlet 8 on Hcreboot7
Note that the camera must be ON
Note that the camera is sensitive to the laser light as well. Try turning off all but one laser and adjusting the power until you can clearly see the marks noted on the images in the snapshots.
Snapshots
Feb 17 2020 snapshots before fine tuning
- These snapshots were taken after the rotation stages were installed in the longitudinal laser path and re-aligned in the Hall
- Rotation stage angles:
- Upper-left: Longitundinal left 2 : 325.5
- Bottom-left: longitudinal left : 263.0
- Upper-right: longitudinal right 2 : 8.80
- Bottom-right: longitudinal right : 0.00
