New Cameras

New cameras are in a plastic bin in the B244 back room.

Procedure

Example: Replacing IPOTR1, IPOTR2, and DSOTR

Occasionally, cameras can get burned by lasers or damaged by radiation. See Figure 1 on the right for an example of how cameras look after they are burned and need to be replaced.


Follow these steps to replace the camera:

  1. Before removing the old cameras, align HeNe to beam marks on FrontView, IPOTR1, IPOTR2, and DSOTR.
    1. This can be done with IP area vented or under vacuum. Note that you will have to realign HeNe going from vacuum to vented and vice-versa.
  2. Replace old cameras with new cameras.
    1. Label cameras and note new serial numbers in the eLog.
    2. Lock the lens or try to remove the lens without adjusting the focus. Remount the camera and reattach the lens.
    3. After replacing the camera, reboot the IOC to connect the new camera.
  3. Verify alignment and focus.
    1. The HeNe should be in the center of the camera image. Update the beam mark for the new location and print to eLog. See Figure 2 on the right.
    2. The “mark” position on the OTR foils should be clear and in focus. You may need to use a flashlight for illumination. Send to eLog. See Figure 3 on the right.

Reset Reboot Count

After the camera has been replaced, reset the reboot count to 0:

[fphysics@facet-srv01 ~/shperez ]$ caput CAMR:LI20:102:REBOOTCOUNT 0


Also double check that the serial number has updated:

[fphysics@facet-srv01 ~/shperez ]$ caget CAMR:LI20:102:SerialNumber_RBV

CAMR:LI20:102:SerialNumber_RBV 50-0503525584
