Abstract
The method developed for proton energy measurement in energy range more than 50 GeV by the instrumentality of thin sampling calorimeter of PAMELA instrument is described. This method is based on a measurement of total deposited energy in calorimeter and usage of certain selection criteria of events. The results were obtained with a Monte Carlo simulation and then were applied to beam test data and flight information. The energy resolution of proton energy measurement remain about 45% for energies up to 10 TeV.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
