Abstract:
The next generation of neutrino experiments is going to use the liquid argon time projection chamber (LAr-TPC) technology. Even though the liquid argon used for the sensitive volume will have a high purity, one can not completely eliminate some radioactive elements like 39Ar and 40K. The electrons produced in the decay of these elements have enough energy to emit Cherenkov radiation, as well as to produce scintillations inside the sensitive volume. In this work the results obtained using Monte Carlo simulations of the Cherenkov and scintillation radiation produced by beta decay electrons will be presented.
