The application, commissioning and development of 2D and 3D X-ray imaging techniques are some of the main tasks of the Imaging group. Therefore, a detector lab has been established at ANKA which is dedicated to R&D of imaging detectors. In this lab, detectors can be characterized, calibrated and tested “off-line”, independently of the synchrotron storage ring status and/ or user operation. Two experimental stations are available in the lab (Figure 1):

  • An X-ray setup, including a high-energy, high-power microfocus X-ray tube (160 kVp, 320 W) and a 5-axispositioning system mounted on an optical breadboard for moving one or more detectors and test samples independently. The X-ray setup is surrounded by a fully accessible lead cabin and can be controlled remotely. The goal is to implement standardized procedures which allow qualitative and quantitative detector testing.
  • A complementary optical setup to characterize the visible light components of indirect converting X-ray detectors. The setup consists of a broad-band visible-light source, as well as a general purpose manipulator mounted on along optical rail. A photodiode is available to measure the transmission of optical components, as well as to calibrate the flux of the light source. In the future, an upgrade with a remotely controllable visible-light monochromator is foreseen. The detectors currently available include indirect converting scintillator-based systems as well as direct converting semiconductor pixel-detector systems. ANKA is part of several collaborations like SCINTAX, Galapad,UFO, the HGF detector initiative, and the Medipix3 collaboration, which all aim for developing and improving X-ray imaging detector systems. The detector lab at ANKA is one big step forward towards playing a major role in these activities.
