Astroparticle physicsAstroparticle physicsTUS space experiment is planned for operation at the Small Space Apparatus (SSA) separated from the main Foton-4 satellite that has to be launched in 2010. Data taking period will be about 3 years to get new data about the energy dependence, composition and anisotropy of CR flux at 10^19 – 10^20 eV. (~ GZK cutoff). The TUS experiment is supposed to be as a pathfinder of the new ambitious KLYPVE/JEM-EUSO experiments on ISS.

NUCLEON space NUCLEON space experimentexperiment is in preparation. The design, production and tests of the NUCLEON trigger system is the JINR responsibility. The trigger module consists of two X, Y planes of 16 scintillator strips. The NUCLEON detector will be launched in orbit in 2009-2010..
