Notes

Below are tables that can be updated with time-ordered information (most recent at top of table):

  • publicly-released geometry files
  • comments for why new geometries might be needed (e.g. detector re-assembled, detector mis-cabled)

For use with all geometry formats used by LCLS (cxidb, crystfel, cctbx, psana).  This page would ideally include simple standalone scripts to convert between formats.

Optical measurements can be found HERE. Corrected optical metrology in text format can be found under the page CSPAD Alignment.

Access to calibration files on disk /reg/g/psdm/detector/alignment/

Camera2_V16_20150120

  • 2015-02-02 -- DS2 chamber with refurbished Camera2 moved to DSA location
    • D50 CsPad rack concentrator was broken.
    • Used D51 CsPad rack for concentrator and motors Februatry 2015 experiments in the SC2 (a.k.a. SC01, 100nm focus chamber). 
      • cxig0715, cxie7015, cxie7515 and cxif5315
      • src = 'DetInfo(CxiDs2.0:Cspad.0)'
      • alias = DsaCsPad
      • relevant epicsStore aliases begin with DsaCsPad:
        • Relative detector Z position:  
          • alias = 'DsaCsPad_z' 
          • pv = 'CXI:DS1:MMS:06.RBV'

  • 2015-03-17 added shield and pipe and moved Camera2 to DS1 chamber

    • CsPad Pipe Al Shield Transmission:

      • 8 um thick polyimide 

      • 1 um thick Al on upstream side

      • 1.75 um thick Al on downstream side

    • The detectors have 0.25 um thick Al coating.

      • --> 3 um total Al

Camera2_V16_20140827

  • Quad 1 (zero based counting) reworked; metrology updated 
  • The other 3 quads (Q0, Q2, Q3) are unchanged (as in the previous metrology: May 14, 2014).
