Characterization of CMOS Active Pixel Sensors for particle detection: Beam test of the four sensors RAPS03 stacked systemIn this work, in order to check the suitability of CMOS Active Pixel Sensors (APS) detectors for vertexing/tracking applications ,four stacked CMOS APS sensors featuring 256x256 pixels with10x10 mm2 size have been tested at the INFN Beam Test Facility (BFT), Frascati (Rome). For this purpose, a dedicated mechanical and electrical setup has been devised and implemented, allowing for the simultaneous read-out of four sensors arranged in a stacked structure. A compact and fast system (up to 64MHz read-out clock) based on external ADCs and FPGA allows for the PC communication through USB2.0.
On the other hand i just wonder, will i also get these nice white pixels if the device is exposed to radiation ?!? Unfortunately there is now video on youtube to that topic, like there is for the ccd by Feb 2
This article proofed what i have guessed. CMOS parts are more insensitive to radiation than ccds are. But the question is can i build a semiconductor radiation detektor/counter with them... by Feb 2
