Abstract
The idea of the KLEM (Kinematic Lightweight Energy Meter) detector is to directly measure the elemental energy spectra of very high-energy cosmic rays in space by determining the angular distribution of secondary particles produced in a target, The first test of the simple KLEM prototype was performed at the CERN SPS test-beam with 180 GeV pions. The results of the first test analysis confirm that, using the KLEM method, the energy of 180 GeV pions can be measured with a relative error of about 67%, which is very close to the results of the simulation (65%).
