Location of the experiment:
NINA 1 and 2 were placed on satellites (Russian Resurs-04 n.1
and Italian MITA); PAMELA will be launched on board a
Russian satellite Resurs-DK1
Test Beams to calibrate and test the detectors: PS and SPS at
CERN, GSI at Darmstadt, Nucleotron at Dubna and TFL at Uppsala
National Responsible: P. Picozza
(Roma2)
1. Goal of the experiment
The goal of the
researches is to study the cosmic ray composition in a wide range
of energies (from few tens of MeV up to some hundreds of GeV),
with particular attention to the antimatter component: positrons,
antiprotons and the search for anti-nuclei with a sensitivity on
the anti-helium/helium ratio better than 10-8.

Activities during 2002:
The objectives of the scientific activity in 2002 were:
- Balloon
Flights: completion of the data analysis for the CAPRICE
flight and publication in international journals.
- NINA1
and 2: completion of NINA1 data analysis and publication
in international journals; progress of NINA2 data
analysis and publications.
- PAMELA:
- Integration
of Mass Dimensional & Thermal Model (MDTM).
- Vibration
tests of MDTM at IABG facility Munchen (Germany).
- Delivery
of MDTM to TsSKB Progress plant (Samara,
Russia) and preliminary integration tests and
compatibility check with Pressurized Container.
- Delivery
to Roma2 and test of Engineering Model (EM) of
CPU.
- Test
at CERN SPS of Flight Tracker, Flight Calorimeter
and Flight Anticounters all integrated with EM of
TRD.
- Test
at CERN PS of low-energy performance of TRD and
Calorimeter.
- Completion
and delivery for integration at Roma2 of Tracker,
Base Plate and S3/TOF.
- Completion
of Flight Model (FM) calorimeter and of FM
Anticounters.
- Completion
of TRD Gas System and PAMELA general cooling
system.
- Delivery
