“…The signal amplitude and the time stamp are stored in an analog and a digital de-randomizing buffers, respectively. The GEMROCs together with dedicated DAQ system offer a unique capability of simultaneous 2D position sensitive and spectroscopic measurements [30,31]. Thus, the system allows measuring the gas gain and energy resolution pixel by pixel.…”

In this paper, we report on the systematic study of different variants of X-ray detectors based on Gas Electron Multiplier (GEM) technology using modified GEM foils with greatly reduced amount of copper. The main goal of this study was understanding the performance of such detectors applied in X-Ray Fluorescence (XRF) elemental analysis. Reduction of the amount of copper in the detector structure is crucial for suppression of XRF background from copper, but one has to ensure that key detector parameters are not affected by such modification. The tested detector variants include detectors with different types of copper-less GEM foils, which have been manufactured starting from standard copper-clad foils and removing partially the copper layer in additional post-processing steps. The results are analyzed and discussed with a particular focus on the energy resolution, uniformity of gas gain and energy resolution across the detector area, and on the long-term stability of the gas gain. Long-term stability tests performed for selected detectors do not indicate for any accelerated aging of the copper-less detectors compared to standard detectors using copper-clad GEM foils. The presented results lead us to conclude that the copper-less GEM detectors are promising devices to suppress the XRF background.

“…The presence of leakage current in detection systems is unavoidable and is related mainly to the sensor performance, some external elements, such as long cables [6], PCB fan-out and package (if used) but also to the ESD protection circuits, which in certain conditions can dominate [7]. The protection circuit is important to protect the electronics against a static discharge during the STS module assembly and partially against sparks when working with GEM detectors (in this case additional, external protection will be mandatory) [8].…”

“…However, in case of a high density readout with a pitch of the readout strips below 1 mm the very first problem with such a solution is caused by the assembly area needed for these components. The ARTROC comprises integrated, silicon proven [9] input protection circuits so it can be used without any additional discrete input protection components.…”

In the paper we report on development of an Application Specific Integrated Circuit (ASIC), called ARTROC, being part of a full-field X-ray fluorescence spectroscopy (XRF) imaging system equipped with a standard three stage Gas Electron Multiplier (GEM) detector of 10 × 10 cm 2 area. The ARTROC consists of 64 independent channels, allowing for simultaneous recording of the amplitudes (energy sub-channel) and time stamps (timing sub-channel) of incoming signals.Thanks to the implemented token-based read out of derandomizing buffers, the ASIC also provides data sparsification and full zero suppression. Reconstruction of the hit positions is performed in an external data acquisition system by matching the time stamps of signals recorded in X-and Y-strips. The amplitude information is used for centre of gravity finding in clusters of signals on neighbouring strips belonging to the same detection events. The ASIC could work in one of six gain modes and one of two speed modes. In a slower mode the maximum count rate per channel is 10 5 /s while in a faster mode it is three times higher. The ARTROC comprises also input protection circuits against possible random discharges inside active detector volume, so it can be used without any additional input components. The ASIC has been designed in 350 nm CMOS process. The basic functionality and parameters have been evaluated using the testability functions implemented in the ASIC design. The ASIC has been also tested in a fully equipped GEM detector set-up with X-rays source.
