摘要

PAMELA is a satellite-borne experiment which is taking data since 2006. It consists of a permanent magneticspectrometer, an electromagnetic calorimeter, a time-of-flight system, a neutron detector and an anticoincidence system.Positrons are a probe of the local galactic environment, allowing secondary production and propagation models to betested. Exotic processes such as dark matter particle annihilations may also produce an excess of positrons at high ener-gies.Combining information from different detectors and in particular from the calorimeter, positrons can be identifiedfrom the overwhelming proton background. The anomalous positron fraction measured by the PAMELA Collaborationin 2009 [1] covers an energy range up to 100 GeV. A new approach for positron identification is described, based on acombination of shower profile variables in the calorimeter, with the aim of extending the positron fraction analysis up to-300 GeV.
