2. Simulated static analysis


There is a relationship between the sensitivity of the cosmic rays experiments and the distance of possible sources. For this reason, a new class of experiments has been programmed on satellite. The satellite which will carry our magnetic spectrometer PAMELA will take off in 2001. The Big Bang description of the origin of the universe suggests that matter and antimatter were present in equal amounts at the beginning. The experimental results (WIZARD and others) obtained until now exclude the presence of large quantities of antimatter, at least within the limits of the current experimental sensitivity.

The experience accumulated for NINA is now being used in the project PAMELA for what concerns the qualification for the employment of devices in space. The silicon-tungsten tracking electromagnetic calorimeter is under the direct responsibility of the Trieste INFN Laboratories. PAMELA is the most ambitious experiment for the search of antimatter in the primary cosmic rays. The Laboratory will undertake the project and the realization of the device following the rigid standards required for the employment in space.
