Chromatic X-Ray imaging with a fine pitch CdTe sensor coupled to a large area photon counting pixel ASIC
R. Bellazzini, G. Spandre, A. Brez +3
An innovative X-ray imaging sensor with intrinsic digital characteristics is presented. It is based on Chromatic Photon Counting technology. The detector is able to count individua…
Imaging with the invisible light
R. Bellazzini, G. Spandre, A. Brez +12
We describe a UV photo-detector with single photon(electron) counting and imaging capability. It is based on a CsI photocathode, a GEM charge multiplier and a self triggering CMOS…
Direct reading of charge multipliers with a self-triggering CMOS analog chip with 105k pixels at 50 micron pitch
R. Bellazzini, G. Spandre, M. Minuti +10
We report on a large active area (15x15mm2), high channel density (470 pixels/mm2), self-triggering CMOS analog chip that we have developed as pixelized charge collecting electrode…
Reading a GEM with a VLSI pixel ASIC used as a direct charge collecting anode
R. Bellazzini, F. Angelini, L. Baldini +11
In MicroPattern Gas Detectors (MPGD) when the pixel size is below 100 micron and the number of pixels is large (above 1000) it is virtually impossible to use the conventional PCB r…
