Drift velocity measurement in gas electron multiplier detectors for application in a time projection chamber polarimeter

CMOS Charge amplifier for liquid argon Time Projection Chamber detectors

1. INTRODUCTION We developed an integrated circuit (IC) for the readout of LAr (Liquid Argon) TPC (Time Projection Chamber) neutrino detectors. These detectors employ LAr simultaneously as massive target and detection medium. The detection of secondary particles produced in neutrino interactions is achieved by collecting, on a system of wires at the sides of the detector, the electric charges f...

Electron Neutrino Classification in Liquid Argon Time Projection Chamber Detector

Neutrinos are one of the least known elementary particles. The detection of neutrinos is an extremely difficult task since they are affected only by weak sub-atomic force or gravity. Therefore large detectors are constructed to reveal neutrino’s properties. Among them the Liquid Argon Time Projection Chamber (LAr-TPC) detectors provide excellent imaging and particle identification ability for s...

Investigation of the operation of Thick Gas Electron Multiplier and Electron Multiplier Assembly for alpha particle detection

In this study, the detection of alpha particles in the high current mode is investigated in the presence of two gaseous electron multipliers in the micro-pattern structures. Thick Gas Electron Multiplier (TGEM) and an Electron Multiplier Assemblies (EMA) were designed and constructed as amplification gap in the detector chamber. An ion chamber is employed to measure the current of interaction b...
