Subject: end of shift summary 

achievements:

  1. found new M2 bender position for focusing using blank
  2. tried to use unfocused beam for ESLITS calibration, but could not see it at SCSPopin, only at M5 Popin
  3. we moved the XRD chamber laterally, closer to hRIXS, to be able to cut the beam using the sample at grazing incidence
  4. seen FEL on antenna, measured FEL spectrum at navitar

problems:

  • general slowness of SA3 motors whenever the whatchdogs were active, switching them off seems at least to mitigate (solve) the problem
  • navitar camera in unknown state
  • scs daq control in unknown state (problem caused by FADC not instantiated)
  • SCS_XTD10_TPI/CAM/SHUTTER was in the UNKNOWN state: the camera cannot be pinged, probably it is disconnected. WE NEED TO FOLLOW UP WITH THIS
  • HSLITS blades were in error and could not be moved, Leandro fixed this problem, the issue was at the PLC level and related to the encoder
  • ESLITS imager and SCS POPin could not be moved, DOC (Dave) fixed this problem
  • we could not propagate the unfocused beam to the SCS Popin, only up to M5 popin

plan:

  • look for signal at the hRXIS
  • optimize resolution by changing LEPM angle
  • measure XAS using MCP
  • look for signal at APD after moving the APD on the side of the sample that is not blocked by the L shaped knife edge
