Magnetized liquid Argon detector for electron charge sign discrimination
A liquid Argon time projection chamber (TPC) immersed in magnetic field is proposed for systematic study and parameter optimisation in electron/muon charge sign discrimination and muon momentum determination by magnetic deflection. Design criteria and preliminary calculation are described. A proof of principle experiment is proposed using an electron beam of 1-10 GeV/c momentum incident on a pr...
متن کاملElectron 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...
متن کاملIonization of liquid argon by a particles
From an analysis of electron pulses in liquid argon produced by a particles the average energy required to form an ion pair is evaluated, assurmng JaEk’s theory of columnar recombination is valid. The mean value of 26.0 ev found in this way agrees well with the corresponding value of 26.4 ev for a particles m argon gas. Application of Jaffk’s theory to the liquid state is discussed, and from th...
متن کاملArDM, a 1t liquid argon detector for dark matter searches
Weak Interacting Massive Particles (WIMPs) are prime candidates for the dark matter in the universe. The ArDM experiment consists of a 1t liquid argon detector to search for WIMPs interacting elastically with argon nuclei. Both scintillation light and ionization charge from nuclear recoils are measured. The 128 nm light is reflected and shifted into the visible range by wavelength shifting foil...
متن کاملPrototyping Liquid Argon Dark Matter Detector
The aim of the project is to build a small ion chamber serving as a prototype of a much larger dark matter detector to be built in the future. This is a brand-new project at Fermilab; my task would be to come up with the prototype ion chamber and a first set of measurements. To start with, the small chamber is going to be filled with Argon extracted from the air, i.e. predominantly 40Ar and tra...
