“…The detector was placed slightly off-center with respect to the neutron beam. This was done in order to avoid a direct irradiation of the whole FPGA behind the detector [15]. Figure 2 shows the intensity profiles along the horizontal and vertical directions on a plane perpendicular to the neutron beam axis, collected over an integrated proton beam current of 355 µAh (with an average proton current <Ip>= 178 µA).…”

A gas detector with a 2D pixel readout is proposed for a future soft x-ray (SXR) tomography with discrimination in energy bands separately per pixel. The detector has three gas electron multiplier foils for the electron amplification and it offers the advantage, compared with the single stage, to be less sensitive to neutrons and gammas. The energy resolution and the detection efficiency of the detector have been accurately studied in the laboratory with continuous SXR spectra produced by an electronic tube and line emissions produced by fluorescence (K, Fe, and Mo) in the range of 3-17 keV. The front-end electronics, working in photon counting mode with a selectable threshold for pulse discrimination, is optimized for high rates. The distribution of the pulse amplitude has been indirectly derived by means of scans of the threshold. Scans in detector gain have also been performed to assess the capability of selecting different energy ranges.

“…Triple-GEM detectors employ the Gas Electron Multiplier (GEM) technology [1] and constitute a promising development. In particular many in many applications of the GEM detectors, like [2], [3], [4], [5], huge advantages can be obtained by the employment of Triple-GEMs, as studied in [6], [7], [8]. Development of Triple-GEM also showed the need of a dedicated interface that could substitute integrated interfaces employed with GEM detectors in the past [9], [10] to meet the new requirements in terms of performance and usability.…”

The recent advances in GEM detector development has led to the requirement of a custom readout to fully exploit the advantages of this technology. GEM detectors can be realized with various shapes, also irregular, and high number of channels. GEMINI has been specifically designed to work with Triple-GEM detectors and it integrates 16 channels to perform readout with both analog and digital signal with Time over Threshold. GEMINI also allows to set a different threshold for every channel to compensate channel inhomogeneity. This work compares simulations with lab measurements and presents results of the imaging of an X-ray source performed with GEMINI.
