YouthSat is a Russian-Indian scientific-educational artificial satellite developed on the basis of an agreement between the Russian Federal Space Agency
and the Indian Space Research Organisation
(ISRO). It is the second satellite in the micro satellite
series being launched by the ISRO.
. The experimental equipment SolRad is intended for registration of hard X-ray radiation within the energy ranges of 10-100 keV, measurements of gamma- radiation within the energy ranges 0.02-5.0 MeV and charged particles: electrons with energy of 0.3-3.0 MeV and protons with energy of 3-100 MeV.
The equipment consists of two parts:
The detecting block contains detecting unit for X-ray and gamma registration, detecting unit for electrons registration, construction elements and electronic cards. The detecting unit for X-ray and gamma registration is a scintillation detector with NaN(Tl) and CsI(Tl) in a single pack overlooked by a photomultiplier. The squares of the crystals is 80x3 mm and 80x77 mm correspondingly. The detecting unit for electrons registration is a telescope composed of four thinlayered (~500 mkm thick) Si detectors with active area of ~6 cm2. In order to extend the energy ranges of the registered charged particles it is planned to insert aluminum layer between the second and the third detectors, and copper layer between the third and the forth detectors. Electronics block provides transmitting of the scientific information to the microsatellite's support systems by 24 analog channels and digital interface. The block consists of the processor, storage elements and buffer cascades, which provide transfer of the signals from the detecting block and data transmission to the on-board telemetry system.
