Description
Castilla-La Mancha Neutron Monitor (CaLMa) is the first installed in Spain and has as mission the continuous measurement of the extra-terrestrial radiation that reaches the ground. Is integrated into the neutron monitors network NMDB (Neutron Monitor Database). A neutron monitor measures the intensity variation of cosmic rays, monitoring solar activity continuously at energy between 1 and 20 GeV.
The CaLMa detector is based on 15 counter tubes, filled with 10BF3 at a pressure of 200 mm Hg. Three of them are standard well-known BP28 Chalk River tubes from the Observatoire Midi Pyrénées and the others twelve are new LND 2061 model. Guadalajara (40º37′N, 3º9′W) is located 55 km away from Madrid at 721 m above sea level. The vertical cut off rigidity is about 6.95 GV, which roughly implies that primary particles with energies above 6.07 GeV/uma could be able to reach the monitor. CaLMa is partially operative from October 2011.
GEANT4 simulations are being developed to get a detailed knowledge of CaLMa response functions to different incident particle populations. We present the preliminary results of the response of CaLMa using Monte-Carlo simulations based on GEANT 4.
