LArTPC
LArTPC stands for Liquid Argon Time Projection Chamber. It is a type of particle detector widely used in particle physics and neutrino physics experiments. These detectors utilize liquid argon as the detection medium. When a charged particle passes through the liquid argon, it ionizes the argon atoms, creating free electrons and ions. An electric field is applied across the detector, causing these ionization charges to drift towards a set of readout planes. The drift time of these charges is measured, providing information about the particle's trajectory in one dimension (the drift direction). The position where the charges are collected on the readout planes provides information about the particle's position in the other two dimensions. This allows for the reconstruction of three-dimensional tracks of charged particles. The excellent particle identification capabilities, high spatial resolution, and ability to detect both electromagnetic and hadronic showers make LArTPCs invaluable tools for studying fundamental particles and forces. Examples of experiments employing LArTPCs include DUNE (Deep Underground Neutrino Experiment) and MicroBooNE.
