Alignment procedure

Alignment procedure for CSPAD2x2 is very similar to CSPAD alignment for quads described in
[PCDS:CSPAD Geometry and Alignment].
The only difference is that CSPAD2x2 has only two 2x1 sensors, that makes everything much simpler.

Software

Is not completely available yet for cspad2x2...

C++ version for psana

data types are implemented in the package pdscalibdata as CsPad2x2* modules:

  • CsPad2x2CenterV1
  • CsPad2x2TiltV1
  • CsPad2x2PedestalsV1
  • CsPad2x2PixelGainV1
  • CsPad2x2PixelStatusV1

Access methods are implemented in the package PSCalib in CSPad2x2CalibPars module.
Example of acess is in PSCalib/test/ex_cspad2x2_calib_pars.cpp.

Automated access to the cspad2x2 geometry parameters is under development.

  • Update module CSPadPixCoords::CSPad2x2ImageProducer
  • Add modules in the package CSPadPixCoords
