The possibility of the construction of the universal telescope on the base of spherical symmetric ioniza-tion calorimeter with a large efficiency "PROTON-5" included to an orbital astrophysical observatory is discussed. The telescope will detect high energy primary cosmic ray particles, determine their elemental and isotopic compositions up to the energy of ~5-10¹⁶ eV. The spectra of gamma rays and primary electrons up to the energy of 10¹³ eV will be measured also.

 

Khrunichev research and production space center, "Salyut" Designers Office and Institute of Control Sciences of the Russian Academy of Science plan development, manufacturing of the Orbital astrophysical observatory "PROTON-5" in structure of International Space Station time of functioning of 20 years. Organizational aspects of realization of teamwork in modern conditions are discussed in work. In structure of the Orbital observatory "PROTON-5" the telescope for studying space beams high energy, having 4π geometry and weight of 10 tons with application on ionization the chambers filled xenon and the angular sanction ~0,5^П is established. The scientific program is realized, namely: measurement of a power spectrum and chemical compound of initial space radiation in a power interval 10^12-5∙10¹⁶ eV, measurement of isotope structure of easy nucleus, measurement in area scale of astronomy and spectra electrons in an interval of energy 5∙10¹¹ - 5∙10¹² eV, searches of an antimatter as antinuclear in a near-earth space, measurement in the field of neutron astronomy, studying positron zones magnetic sphere the Earth.

The experimental data obtained by the orbital telescope "Proton-5" allow to find the answers on a number of fundamental questions of high energy particle astrophysics, namely. Now the V.A. Trapeznikov Institute of control sciences of RAS is engaged in the work on the project of the long-term orbital astrophysical observatory which includes the "Proton-5" telescope. The first closing stage of this work must be a sketch project, mathematical modeling, manufacturing of a pre-production model and realization of graduation on the accelerator.

The realization of this project will be useful if scientists from different countries are take part in this work. The contribution of these scientists in the project could be the most significant on the stage of sketch project elaboration.

In ICS the Russian Academy of Science the operational experience on adaptive control, control of movement and navigation of flying devices, the onboard information control system that will allow to equip an orbital astrophysical observatory with modern onboard computer facilities is saved up.
