The Development of Tritium Identification Method for the PAMELA Experiment

This article focuses on the development of the method of cosmic ray tritium nuclei identification based on data of the PAMELA experiment which is installed on board satellite Resurs-DK1. The tritium nuclei identification was implemented by measuring the particle rigidity and velocity, as well as energy losses in the tracker detectors. We discuss the method of tritium separation on the background of other nuclei. The criteria for event selection allow distinguishing tritium nuclei in the magnetic rigidity range 0.5 – 3.0 GV.
