“…In a parallel way, the use of nanostructures of germanium deposited in silicon to obtain small APDs able to work at voltages of only 1.5V and speeds of 30GHz have been proposed (Assefa et al, 2010). Even, a novel effort to use APDs to construct detectors for charged particles has recently been reported (Graugés et al, 2010. Results suggest that, through control of the doping concentration, devices with a much improved fill factor could be achieved.…”

“…The detector was designed to have a sensitive area of 1 Â 1 mm 2 in order to facilitate the observation of particle traces. In addition, the sensor size was fixed to 20 Â 100 mm 2 [22] to achieve a good fill factor (88%). The detector is organized in 10 rows (m) per 43 columns (n) of pixels.…”

Keywords:The Geiger-mode avalanche photodiode (GAPD) CMOS EUDET/AIDA telescope Schottky detector Test beam Trigger logic unit (TLU). a b s t r a c tIt is well known that avalanche photodiodes operated in the Geiger mode above the breakdown voltage offer a virtually infinite gain and time accuracy in the picosecond range that can be used for single photon detection. However, their performance in particle detection still remains unexplored. In this contribution, we are going to expose different steps that we have taken in order to prove the efficiency of the Geiger mode avalanche photodiodes in the aforementioned field. In particular, we will present a setup for the characterization of these sensors in a test beam. The expected results of the test beam at DESY and CERN have been simulated with Geant4 and will also be exposed.

This work presents low noise readout circuits for silicon pixel detectors based on Geiger mode avalanche photodiodes. Geiger mode avalanche photodiodes offer a high intrinsic gain as well as an excellent timing accuracy. In addition, they can be compatible with standard CMOS technologies. However, they suffer from a high intrinsic noise, which induces false counts indistinguishable from real events and represents an increase of the readout electronics area to store the false counts. We have developed new front-end electronic circuitry for Geiger mode avalanche photodiodes in a conventional 0.35 µm HV-CMOS technology based on a gated mode of operation that allows low noise operation. The performance of the pixel detector is triggered and synchronized with the particle beam thanks to the gated acquisition. The circuits allow low reverse bias overvoltage operation which also improves the noise figures. Experimental characterization of the fabricated front-end circuit is presented in this work.
