We exploited the crossing muon data, collected in the 501 liquid argon TPC exposed at the CERN neutrino beam in 1997, to investigate the possibility of identifying the direction of minimum ionizing particle tracks relying only on delta-rays orientation. In this note we show that simple selection criteria allow using delta-rays down to very low energy (few MeV) with high efficiency and no misidentification of their direction. The Monte Carlo prediction - two recognized delta-rays per meter of track - is very well matched by the result of the scanning of the experimental data.

Abstract
We exploited the crossing muon data, collected in the 501 liquid argon TPC exposed at the CERN neutrino beam in 1997, to investigate the possibility of identifying the direction of minimum ionizing particle tracks relying only on delta-rays orientation. In this note we show that simple selection criteria allow using delta-rays down to very low energy (few MeV) with high efficiency and no misidentification of their direction. The Monte Carlo prediction - two recognized delta-rays per meter of track - is very well matched by the result of the scanning of the experimental data.File in questo prodotto:
