QXRD 64bit version

2011-Nov-01 | Tags: freeware

Start64!QXRD is software for the acquisition and analysis of X-ray data taken with 2 dimensional detectors. The software can drive a Perkin Elmer XRD series flat panel detector and can be remote-controlled via a socket interface, or directly from SPEC


  • Control 2-D X-Ray Detectors
  • Multithreaded data processing
  • Powder Diffraction, SAXS and PDF processing

System Requirements

  • QXRD requires a windows system with the appropriate Perkin Elmer frame grabber card and drivers installed.
  • Perkin Elmer provides three frame grabbers for their detectors - the PCI and PCI-X frame grabber both work with 32 bit Windows 2000 and Windows XP, the newer PCI-Express grabber works also with 32 and 64 bit Windows Vista and Windows 7.
  • At least 1GB of memory is recommended, preferably 2-4GB.
  • QXRD will take advantage of a multicore processor, if present. I recommend at least four cores.
  • At maximum readout rate the detector can produce 15 2k x 2k x 2byte images per second, corresponding to a data rate of 120MB per second. If you intend to use the detector at maximum rate for long sequences of images you'll need a fast disk drive - I would recommend either a RAID-0 setup or a solid state disk.
  • I'd recommend a monitor with at least 1600x1200 pixel resolution - while the QXRD display can be squeezed onto a smaller display it is significantly more convenient on a higher resolution display.
  • QXRD can also run on 32 and 64 bit linux systems, with the caveat that there is (currently) no detector support. It can still be used for processing and visualising data acquired by other means.
