"Design and low temperature characterization of low noise single photon\r\ndetector arrays for rare event search experiments with liquid noble gases"^^ . "Dark matter search experiments, with liquid noble gas targets, require a detector with a low noise\r\nand a high VUV-light sensitivity. Within this thesis it was evaluate whether Digital SiPMs are a\r\nsuitable candidate. For this, a test-array was developed and characterized at low temperatures.\r\nThe advantage of digital SiPMs is that Single Photon Avalanche Diodes (SPAD) are manufactured\r\nin a CMOS process so that the readout logic can be placed on the same chip. The output signals\r\nare digital, and no readout chip is required, as in the case with common SiPMs. The test array was\r\noptimized for a high-fill-factor and possesses a low-power data-driven readout. It houses SPADs\r\nof different geometries, to investigate the noise as a function of size and shape. Furthermore,\r\noptimizations for the SPAD noise at cold temperatures, were made. At low temperatures of\r\nT = 165 K a dark count rate independent of the geometry of 0.02 Hz per mm2 of active area,\r\nwas observed. An optimal SPAD size was found, for which the fill-factor is 74% when the noisy\r\nSPADs are turned off and, finally, a power dissipation of some ∼2 m W was observed. Based on\r\nthis, a high fill-factor array with a data-driven readout was developed."^^ . "2022" . . . . . . . "Michael"^^ . "Keller"^^ . "Michael Keller"^^ . . . . . .
