Folks,

 

R9-6 of the quadEM module is now available.  These are the release notes:

 

  • Added a software driver to get data into the quadEM. It is similar to the NDDriverStdArrays for areaDetector. Thanks to Xiaoqiang Wang from PSI for this.
  • Added support for the SenSiC PCR4 picoammeter. Thanks to Sammy Mosca from STLab for this.
  • Added support for the Sydor T4U electrometer. There are 2 implementations for this:
    • T4UDirect: The quadEM driver communicates directly with the T4U.
    • T4U: The quadEM driver communicates with the T4U via a Sydor program. Thanks to Iain Marcuson from Sydor for these.
  • Supported a variant of the Square geometry, where the diodes are arranged counterclockwise. Thanks to Xiaoqiang Wang from PSI for this.
  • Converted the documentation from raw HTML to Sphinx, published at https://epics-modules.github.io/quadEM.
    • Added documentation about scanning with the TetrAMM
    • Added documentation about streaming data to disk with HDF5 plugin
    • Added documentation about using feedback, with an example of pitch feedback on a monochromator.
    • Improved the documentation about plugins.
  • Converted the release notes from raw HTML to RELEASE.md.
  • Added a Word document of a study of noise with the TetrAMM.
  • Removed support for the APS_EM, since this is no longer available or in use. Note that this changes the enum values for all models, and so the new quadEM.* OPI screens are required.
  • Load ADCore/iocBoot/commonPlugins.cmd for all example IOCs.
    • The Plugins/ menu on quadEM.adl now has the following 3 menu items:
      • QE common plugins
      • QE FFT plugins
      • AD common plugins
    • AD common plugins provides all standard areaDetector plugins including ROIs, HDF5, etc.
    • It is now possible to stream data an HDF5 file, for example. This can be sampling at up to 20 kHz on the TetrAMM.
  • Simplify the autosave files to reduce redundancy.
