Description
We present the performances and characterization of a detector array made of S13370-3050CN, VUV4 generation of Multi-Pixel Photon Counter manufactured by Hamamatsu, sensitive to vacuum ultraviolet (VUV) light, in the range of interest of the xenon scintillation. The array is equipped with a low power consumption preamplifier electronics and can be operated at liquid xenon temperature (175 K). The electronics is meant for the readout of a 8 by 8 matrix of individual photosensors and it is based on the use of a single operational amplifier. The system is also provided with a biasing correction circuit for the gain equalization of photosensors with different breakdown voltages. Depending on the application, the electronics can house different models of operational amplifiers.
The results show a pronounced single photon detection capability opening for its use in dark matter search with liquid xenon target. The detailed simulation of noise contributions to the overall noise suggests a dominant component related to photosensor characteristics, while the contribution of the electronic noise sources is negligible.
The results of a one to one comparison between detector prototype and R11410 photomultiplier tube obtained by measuring the intensity of VUV light selected in step of 1 nm and delivered by a monochromator, are also presented.
