Liquid Argon detector development at Sheffield

by Dr Nicola McConkey

Liquid argon is an excellent detector medium, with good scintillation and charge transport properties. For this reason, it is widely used both in rare event physics and medical physics, with a current prevalence in neutrino physics as the basis of both the long baseline experiment DUNE, and the short baseline experiment at Fermilab. At Sheffield we are developing technology to be used in liquid argon detectors; in this talk I will primarily focus on two devices, a cryogenic cmos camera system used for high voltage monitoring in large volume detectors, and a Gaseous Photomultipler being developed for use in PET detectors for medical physics. I will discuss the technology, the detectors, and the relevance of using these devices in the current field.
