Bring Up the Beamline Cameras
camViewer
- Type
> camViewer
in a terminal - It opens the
dg1_yag
camera by default - The drop-off menu gives a list of cameras. The ones starting cxi are most relevant. However, we do occasionally need to bring up other beamline cameras for FEL diagnostics, e.g., the upper stream
xcs_yag3m
camera. > camViewer -c cameraName
brings up a specific camera with the name> camViewer -c cameraName -m
brings up the EDM control panel for manual controls> camViewer -c cameraName -r
resets the camera IOC
cxi_dg1_yag
- This is at the beginning of the hutch, the YAG/camera is after the DG1 slits
- Looking at this camera for DG1 slits
- The YAG/camera is after the pre-focus lens
- Looking at this camera for centering the pre-focus lens to the DG1 slits
- Everything is aligned to DG1 slits
- Align all other apertures, including the slits and lenses to the DG1 slits
- If the FEL is off, pointing it with HOMS mirror or ACR undulator
- Use undulators to adjust the vertical pointing
- Use HOMS mirror to adjust the horizontal pointing
- Never change the position of DG1 but sometimes the width
- Don’t home the motors
- Don’t change the centers
cxi_dg2_yag
- The YAG/camera is after the KB1 up and down slits, and DG2 slits
- Looking at this camera for centering these slits to the DG1 slits
- The YAG/camera is after the DG2 lens
- Looking at this camera for centering the DG2 lens to the DG1 slits
- The time tool sample paddle is in the DSB chamber
- Use this camera to see the stack of time tool targets
cxi_sc1_inline
- The sc1_inline holely mirror is in the SC1 chamber, which couples the light out of the chamber and imaged by the Questar tele-lens
- Looking at this camera for centering the DSB slits and the SC1 piezo slits to the DG1 slits
- It is used to look at the interaction point (IP)/gas cell & pinhole, and the frosted YAG attached to the gas cell
- The YAG is used for checking the laser and X-ray spatial overlap
cxi_sc3_inline_opal
- The sc3_inline holely mirror is in the SC3/SSC chamber, which couples the light out of the chamber and imaged by the Questar tele-lens
- It projects the image of X-ray beam after the gas cell
- Use this camera to align the gas cell x & y, pitch & yaw using the unfocused X-ray beam
- Use this camera to align the pinhole x & y using the unfocused X-ray beam
- We have replaced the slow OPAL with a Manta GigE, maybe we should change the name and camera info in the camViewer -c cxi_sc3_inline_opal -m too.
