Whether for inelastic scattering or fusion-plasma diagnostics, specific solutions based on our hybrid photon counting detector platforms enable construction of superior X-ray spectrometers.
High-resolution X-ray spectroscopy of fusion reactor plasmas benefits from the noise-free photon counting and high frame rates of HPC detectors.This detector system was designed for the Institute of Plasma Physics in Hefei, China. The detector head was comprised of nine PILATUS modules. It was part of an X-ray imaging crystal spectrometer (XICS) for the detection of X-rays in the energy range from 3.1 keV (Ar emission) to 13 keV (Kr emission) at EAST Tokamak. The fast readout time of only 0.95 ms and the high frame rate of 500 Hz, enabled by the PILATUS3 technology, provided real-time feedback for the experiment. DECTRIS has a history in supplying detectors for plasma spectroscopy based on a long-lasting and successful relationship with the Princeton Plasma Physics Laboratory.
“Our collaboration with DECTRIS led to significant improvements of the high-resolution X-ray spectroscopy of hot Tokamak and stellarator plasmas. Thanks to the implementation of noise-free, single-photon counting detectors from DECTRIS in our x-ray imaging crystal spectrometers, it is now possible to perform Doppler measurements of the ion temperature and plasma flow velocity profiles with much higher temporal and spatial resolutions than was previously feasible.”

This EIGER X 1M-MAX IV incorporated a highly compact design for the X-ray emission spectrometer SCANIA-2D at the Balder beamline at MAX IV. The detector consisted of a short detector head, with all connectors on the side of the housing and a separate electronics box. This custom design made the photon counting detector compatible with the limited space available inside the spectrometer. It allows for a maximum radius of the Rowland circle below the beam, while leaving free space for in-situ environments above the beam. In addition, defined mounting points on the housing were implemented that held fiducial markers for optical detection of the exact detector position in three dimensions.
