Abstract
The PAMELA cosmic-ray telescope has been launched into space on 15 June 2006 on board of the Resurs-DK1 Russian satellite and is in continuous data acquisition mode since 11 July 2006. The magnetic spectrometer of PAMELA is composed of a hollow permanent magnet with a microstrip Si tracking system inserted inside the cavity. This paper reviews the general characteristics of the tracking system and presents a preliminary analysis of a data sample acquired in flight, showing that the main performances of the Si detectors after launch are in agreement with what expected on the basis of the ground qualification tests.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
