The dual neutron/gamma-ray sensitivity of organic scintillators makes them suitable for a wide range of nuclear measurement applications, including nuclear nonproliferation, nuclear medicine, and fundamental physics. Pulse shape discrimination techniques enable distinguishing interactions of different particle types and are typically implemented with simple analog techniques or digital renditions…

Accurate single photoelectron (SPE) characterization of photosensors is essential for controlling systematic uncertainties in low-light neutrino and dark matter detectors. We present a compact laboratory setup for the characterization of photosensors under controlled, low-light conditions. Specifically, we demonstrate its use with photomultiplier tubes (PMTs) operated at the SPE-level, using pico…

Time-differential perturbed angular correlation (TDPAC) spectroscopy is a nuclear solid-state technique that requires high energy and coincidence-time resolutions from scintillation crystals and photodetectors. Traditionally, photomultiplier tubes (PMTs) have been coupled to LaBr 3 :Ce crystals; however, they have been replaced by Multi Pixel Photon Counters (MPPCs) for TDPAC experiments conducte…
