Noble liquid elements are excellent scintillators with high light yield in the vacuum ultraviolet (VUV) spectral range. The detection of this VUV scintillation light poses a considerable instrumentation challenge, as it requires highly sensitive photodetection systems in a range not covered by most of the commercially available sensors. Improving photon detection efficiency in noble liquid element detectors is essential to enhance the performance and extend the physics reach of upcoming and future experiments.
We are working on the development and characterization of VUV cryogenic silicon photomultipliers (SiPMs) as well as front-end electronics, DAQ systems and online algorithms for signal processing, triggering and event selection. In parallel, we are optimizing photon traps coupled to SiPMs for the detection of photons over large areas, which is crucial for the scalability of current detectors. We have started an R&D on a monolithic light-charge pixel-based readout with the combination of charge readout pads and VUV SiPM light readout on the same PCB plane. This technology offers new possibilities to lower energy thresholds and improve the energy resolution. We are also involved in reconstruction techniques including machine learning.
In this talk we will present the status of our R&D at CIEMAT and the development of specific instrumentation and cryogenic infrastructures.
