MPGD technology has recently been adopted for soft X-ray fluorescence detection techniques. The MPGD are relatively cheap detectors with capability of detection not only a deposited energy (inside its active volume) but also a position of an absorbed photon or a charged particle. Nevertheless, the MPGD’s development is mainly driven by HEP experiments needs, recently many new application in...
The new design concept of the Micro Pixel Chamber ($\mathrm{\mu}$-PIC) has been developed and tested for charged particles tracking. The $\mathrm{\mu}$-PIC is a 2D gaseous imaging detector made by the PCB technique. One of the most important property is that the $\mathrm{\mu}$-PIC does not require any floating structures and stretching processes.
For protecting the $\mathrm{\mu}$-PIC from...
The deformed shape of the perforated holes in the Gas Electron Multiplier (GEM) are proven to have great effect on the electron gain. Numerical calculations are required to optimized the GEM sheet configuration for maximum gain. In this paper, three methods are used to numerically predict the nonlinear mechanical properties of the GEM foil using finite element method. The hexagonal pattern of...
The Resistive-Plate WELL (RPWELL) detector is a single-element gas-avalanche multiplier, combining a single-faced THGEM electrode coupled to the segmented readout anode through a sheet of large bulk resistivity. Laboratory and accelerator studies, performed in Ne- and Ar-based gas mixtures, have demonstrated its large dynamic range (from one to several thousand electrons), high achievable...
