ABSTRACT: This article reports nine solar energetic particle (SEP) events detected by the New Instrument for Nuclear Analysis (NINA) between 1998 October and 1999 April. NINA is a silicon-based particle detector mounted on board the Russian satellite Resurs-01-4, which has flown at an altitude of about 800 km in polar inclination since 1998 July. For every solar event, the power-law 4He spectrum across the energy interval 10-50 MeV nucleon-1 was reconstructed and spectral indexes, γ, from 1.8 to 6.8 extracted. Data of 3He and 4He were used to determine the 3He/4He ratio, which for some SEP events indicated an enrichment in 3He. For the 1998 November 7 event, the ratio reached a maximum value of 0.33 ± 0.06, with spectral indexes of γ = 2.5 ± 0.6 and γ = 3.7 ± 0.3 for 3He and 4He, respectively. The 3He/4He ratio averaged over the remaining events was 0.011 ± 0.004. For all events, a deuterium-to-proton ratio was estimated. An upper limit on the average value over all events was 2H/1H < 4 × 10-5 across the energy interval 9-12 MeV nucleon-1. Upper limits on the 3H/1H counting ratio for all events were determined. For the 1998 November 14 SEP event, the high flux of heavy particles detected made it possible to reconstruct the carbon, nitrogen, and oxygen flux.

ABSTRACT: PAMELA is a satellite-borne experiment that will study the antiproton and positron fluxes in cosmic rays in a wide range of energy (from 80 MeV up to 190 GeV for antiprotons and from 50 MeV up to 270 GeV for positrons) and with high statistics, and that will measure the antihelium/helium ratio with a sensitivity of the order of 10<sup>-8</sup>. The detector will fly on-board a polar orbiting Resurs DK1 satellite, which will be launched into space by a Soyuz rocket in 2004 from Baikonur cosmodrome in Kazakhstan, for a 3-year-long mission. Particle identification and energy measurements are performed in the PAMELA apparatus using the following subdetectors: a magnetic spectrometer made up of a permanent magnet equipped with double-sided microstrip silicon detectors, an electromagnetic imaging calorimeter composed of layers of tungsten absorber and silicon detectors planes, a transition radiation detector made of straw tubes interleaved with carbon fiber radiators, a plastic scintillator time-of-flight and trigger system, a set of anticounter plastic scintillator detectors, and a neutron detector. The features of the detectors and the main results obtained in beam test sessions are presented.

ABSTRACT: We present in this paper a status report of the space experiment PAMELA. PAMELA is a satellite-borne experiment which primarily aims to measure the antiproton and positron spectra in the cosmic radiation over a large energy range (from 80 MeV up to 190 GeV for antiprotons and from 50 MeV up to 270 GeV for positrons) and to search for antinuclei with a sensitivity of the order of 10(-8) in the antihelium/ helium ratio. In addition, it will measure the light nucleax component of cosmic rays and investigate phenomena connected with Solar and Earth physics. The apparatus will be installed onboard the polar orbiting Resurs DK1 satellite, which will be launched into space by a Soyuz TM2 rocket in 2004 from Baikonur cosmodrome in Kazakhstan, for a 3 year long mission. PAMELA consists of: a time of flight system, a transition radiation detector, a magnetic spectrometer, an anticoincidence detector, an electromagnetic imaging calorimeter, a shower tail catcher scintillator and a neutron detector.

ABSTRACT: In this paper we report on the energy spectra and abundance ratios of hydrogen and helium isotopes of albedo origin, measured by the instruments NINA and NINA-2 in near-equatorial regions. The instrument NINA flew on board the satellite Resurs-01-N4 between 1998 and 1999, at a 830 km average altitude. The NINA-2 apparatus, on board the satellite MITA, was put into orbit in July 2000 at an altitude of about 450 km. NINA and NINA-2 measurements revealed that H-2, H-3, He-3, and He-4 are a significant portion of the secondary flux above the atmosphere. The energy spectra of hydrogen isotopes are practically flat across the energy range of 10-40 MeV/n, while the spectra of helium isotopes can be fitted by a power law of spectral indexes gamma=0.8 and gamma=1.5 for He-3 and He-4, respectively.

ABSTRACT: In this paper we report on the energy spectrum of protons of albedo origin measured by the instruments NINA and NINA-2 at different geomagnetic locations, and the be-haviour of the proton flux as a function of altitude out of the South Atlantic Anomaly. The instrument NINA was used on board the satellite Resurs-01-N4 between 1998 and 1999, at an altitude of about 830 km. The NINA-2 apparatus, on board the satellite MITA, was put into orbit in July 2000, at an altitude of about 450 km. A detailed understanding of the fluxes of charged particles in near Earth orbit is important to reach an accurate theoretical description of the Earth's mag-netic field, but also as input for the calculation of the back-ground for scientific instruments aboard satellites, like the future AGILE and GLAST γ astronomy telescopes.

ABSTRACT: The satellite MITA was launched on July the 15 th , 2000 from the cosmodrome of Plesetsk (Russia) with a Cosmos-3M rocket. MITA carries the payload NINA-2 for the study of solar and galactic cosmic rays. The detector used in this mission is identical to the one already flying on the Russian satellite Resurs-O1 n.4 in a 840 km sun-synchronous orbit, but makes use of the extensive computer and telemetry capabilities of MITA bus to improve the active data acquisition time. The scientific objectives of NINA are the study of cosmic nuclei from hydrogen to iron in the energy range between 10 MeV/n and 1 GeV/n during solar maximum period. The device is capable of charge identification up to iron with isotope sensitivity up to oxigen. The 87.3 degrees, 460 km altitude polar orbit allows investigations of cosmic rays of solar and galactic origin as well as the trapped component. In this work we present preliminary results concerning particle identification capabilities and nuclear differential spectra for helium, carbon and oxygen in the energy range between 10 and 50 MeV/n.

ABSTRACT: SilEye-2 is a silicon detector telescope built for the study of the causes of Light Flashes perception by astronauts. As a stand-alone device, it can also monitor the real time radiation composition inside MIR. The device was operational for more than 1000 hours in the years 1998-2000, detecting also several Solar Particle Events. In this work we show the nuclear discrimination capabilities of the device and nuclear abundance data from Boron to Silicon above 150 MeV/n. We also present Linear Energy Transfer measurements inside MIR.

ABSTRACT: Observations of 9 Solar Energetic Particle events detected by the instrument NINA from November 1998 to April 1999 will be presented. NINA is a silicon-based space detector in orbit since July 1998 on board the Russian satellite Resurs-01-N4, which flies at low altitude (about 800 km) in polar inclination. For every SEP event we reconstructed the power-law 4 He spectrum in the energy interval 10–50 MeV/n, extracting spectral indexes from 1.8 to 6.8. Data of 3 He and 4 He were then employed to determine the 3 He/ 4 He ratio, that turned out to be high for some SEP events showing the enrichment in 3 He. For the 7 November 1998 event this ratio reached the maximum value of 0.33 ± 0.06, with spectral indexes 2.5 ± 0.6 and 3.7 ± 0.3 for 3 He and 4 He, respectively. The 3 He/ 4 He ratio averaged over the remaining events was 0.011 ± 0.004. For all events we determined the deuterium-to-proton ratio. The average value of the 2 H/ 1 H ratio, over all events, was (3.9±1.4)× 10 −5 in the energy interval 9–12 MeV/n. During 24 November 1998 event, however, this ratio resulted about 10 times higher than normal coronal values.
