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

timetoolCam

• 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.
