Abstract
In last years, the interest on LAr TPC used for neutrino physics and dark matter searches is growing; the knowledge of transport properties of Ar electrons is essential to extract faithful physical information. In particular there is a lack of experimental measurements on diffusion parameter. Dedicated runs for this measurement were carried out with the ICARUS T600 detector considering cosmic muons collected at different electric field.
Highlights
The diffusion of electrons drifting in an electric field is an important effect contributing to the spatial resolution of a Liquid Argon Time Projection Chamber (LAr TPC) detector
The T600 detector is composed by four LAr TPCs with a drift length of 1.5 m each; only the longitudinal diffusion can be measured, because the transversal one is hidden by the detector characteristics
Evaluation of longitudinal diffusion parameter After the calculation of the drift velocity, each muon sample is processed with the hit finding procedure
