Description

Large variations in muon flux above 1 GeV observed in GRAPES-3 muon telescope are a result of their acceleration in atmospheric electric fields. To interpret this phenomenon, detailed Monte Carlo simulations were carried out by using CORSIKA package. The effects of applied electric field can be studied with the option ’EFIELD’ available in CORSIKA. However, this option works only for electrons and positrons. Therefore, the variation observed in GRAPES-3 muon flux can not be simulated. Therefore we implemented an extended ’EFIELD’ option to simulate applied electric field on charged pions, kaons and muons. This extension also allows user to define cloud height where electric field exists. Initial simulations show that at high electric potential, the muon flux decreases irrespective of polarity. The simulation results will be presented at the conference.
