The nEXO experiment is a planned tonne-scale search for neutrinoless double beta decay (0$\nu\beta\beta$) in $^{136}$Xe. In a single-phase liquid xenon time-projection chamber, ionization electrons and scintillation light will be recorded to reconstruct, among other parameters, the deposited energy of an event. Silicon Photomultipliers (SiPMs) have been chosen by the nEXO collaboration to...
Silicon photomultipliers (SiPMs) are emerging as the photodetector technology to be used in upcoming noble liquid experiments. Features that make SiPMs an ideal candidate to detect light signals include their compact size, insensitivity to magnetic field, high gain, low operating voltage, low dark noise rate and sensitivity to single photon counting. Newly developed SiPMs sensitive to vacuum...
The Super-Kamiokande (Super-K) is a neutrino detector in Japan that aims to study neutrino sources (atmospheric, solar, supernovae), search for proton decay, measure neutrino oscillation and accelerator neutrinos. It contains ~11,000 photomultiplier tubes (PMTs) surrounding a massive tank filled with 50 ktons of ultra-pure water.
One of the limiting factors for more measurements of neutrino...
Neutrinoless double beta decay (NLDBD) is one of the most important searches in particle physics nowadays. If discovered, it may help to answer some of the unanswered questions in physics, shedding light on the neutrino masses and helping explain the origin of matter in the universe. One of the most promising isotopes to search for NLDBD is 136Xe. The only existing method in the market for...
The Hyper-Kamiokande experiment uses water-Cherenkov detectors to study neutrino oscillation and CP violation with high precision. To reduce systematic errors, multi-photomultiplier tube modules (mPMTs) that comprise the detectors will include LED light sources for calibration purposes. This talk describes how the LEDs are incorporated into mPMT design, how the distribution of LED light is...
