Alignment procedure

Alignment procedure for CSPAD2x2 is very similar to CSPAD alignment for quads described in
 CSPAD Geometry and Alignment.
The only difference is that CSPAD2x2 has only two 2x1 sensors, that makes everything much simplerbut with different memory model as explained below.

Optical measurements

Photos and charts with numeration of corners in otical measurements:

Metrology table

Metrolody files from different optical measurements are collected in directories with specific dates under


<PATHREPO>/detector/alignment/cspad2x2/

Example of the 1-st metrology Metrology table in xlsx format:
Metrology-140ks-Feb13-2013.xlsx

Calibration types

In 2014 new universal detector geometry software is implemented and documented in the Detector Geometry page. In this approach detector geometry calibration information is located in a single file of type

...

  • center - x, y, z center position for each two 2x1 in the detector. Obtained from optical measurement.
  • tilt- two 2x1-tilt angle for the detector in fractional degree. Obtained from optical measurement.

Note

Calibration types center and tilt are deprecated and supported for backward compatibility.

Type geometry is used by default in all current applications.

Note from Gabriel and Philip
 Note
Philip and I inspected the CSPAD 140Ks that we received last week (CSPAD 1,2,3,5):
- CSPADs 1, 2 and 5 have the same metrology as that on February 13, 2013.
- CSPAD 3 has been fixed meanwhile (initially it contained 2x2 module #111, which is the one in your metrology file). Now its 2x2 module is replaced with #7 (metrology file attached). This metrology file should be applied in all experiments that took place after the service date. To find out this date, we will consult with you further.
- CSPAD 4 is only a mechanical assembly (see other e-mail sent a few weeks ago).
Thanks,
Gabriel and Philip

Cspad2x2.4

Software
Access interface to any detector data and calibration parameters is implemented in Python Package Detector.
CSPAD2x2 memory data model
In contrast to CSPAD which data array shape is (N, 185, 388), the CSPAD2x2 data array has a shape (185, 388, 2); the memory pointer increment by 1 swaps the 2x1 sensor. The (raw,column)=(0,0) is located in corners 4 and 8 of optical measurement scheme for two 2x1 sensors, respectively.
...
In 2014 new universal detector geometry software is implemented and documented in the Detector Geometry page. In this approach detector geometry calibration information is collected in a single file of type
  • geometry
which contains hierarchical description of all detector components. For example for CSPAD it has sensors' location and rotation in the quads, quads - in the detector, detector - in the setup, etc.
By default these files reside under the calib directory with full path like
  • /reg/d/psdm/<instrument>/<experiment>/calib/<calib-soft-version>/<data-source>/geometry/<run-range>.data
Whenever necessary image can be generated by the psana Module CSPadPixCoords::CSPad2x2ImageProducer, which access geometry calibration data automatically, generates 2-d image and saves it in the event store for further processing.
...
Alternatively, Python modules for CSPAD2x2 geometry are available in the package PyCSPadImage documented in CSPAD pixel coordinates and image producer in Python. They provides an interface for getting
(tick) Calibration parameters from DB and local directory,
(tick) Pixel coordinates,
(tick) Image producer
...

Deprecated
C++ classes and modules for psana
(tick) data types are implemented in the package pdscalibdata as CsPad2x2* modules:
  • CsPad2x2CenterV1
  • CsPad2x2TiltV1
  • CsPad2x2PedestalsV1
  • CsPad2x2PixelGainV1
  • CsPad2x2PixelStatusV1
(tick) Access methods are implemented in the package PSCalib in CSPad2x2CalibPars module.
Example of acess is in PSCalib/test/ex_cspad2x2_calib_pars.cpp.
(tick) Automated access to the cspad2x2 geometry parameters is implemented in packages:
  • Package CSPadPixCoords generates and returns the CSPad2x2 pixel coordinates, taking into account geometry alignment parameters, if available in the expected place under /reg/d/psdm/<instrument>/<experiment>/calib directory.
  • Module CSPadPixCoords::CSPad2x2ImageProducer produces CSPad2x2 image, accounting for correct geometry, if available.
