摘要：

The PAMELA equipment will be assembled in 2001 and installed on board the Russian satellite Resurs. PAMELA is conceived mainly to study the antiproton and positron fluxes in cosmic rays up to high energy (190 GeV for (p) over bar and 270 GeV for e(+)) and to search antinuclei, up to 30 GeV/n, with a sensitivity of 10(-7) in the He/He ratio. The PAMELA telescope consists of. a magnetic spectrometer made up of a permanent magnet system equipped with double sided microstrip silicon detectors a transition radiation detector made up of active layers of proportional straw tubes interleaved with carbon fibre radiators; and a silicon-tungsten imaging calorimeter made up of layers of tungsten absorbers and silicon detector planes. A time-of-flight system and anti-coincidence counters complete the PAMELA equipment. In the past years, tests have been done on each subdetector of PAMELA; the main results are presented and their implications on the anti-particles identification capability in cosmic rays are discussed here.
