[en] The results of investigation of compression plasma heating in a closed trap ''Compact tor'' are reported. The problems have been set: output to the kiloelectronvoltage border and direct demonstration of compact tor compression heating in a collisionless parameter region, investigation of stability and losses in the processes of formation of a closed structure, development and relaxation of shock flows, injection and tor slowing down. The ion temperature Tsub(i) approximately equal to 1 keV is obtained. Total neutron emission up to 6x10⁷ neutrons for a pulse is registered. The stability of the poloidal stucture in the most dangerous pulse processes, such as formation of an extended antiparallel magnetic configuration and closed trap, development and relaxation of shock flows, fast plasma pressure jumps, sharp compact tor form evolution and establishing of tor equilibrium, tor injection and slowing down. An essentially collisionless process nature (relaxation time tau approximately 3 μs, tausub(ii) approximately 30 μs) has been found out. Thus, the results being in agreement with the previous studies on key moments of the compact tor represent simultaneously qualitatively a new level as they belong to the collisionless region. This gives physical reasons for extrapolation up to thermonuclear parameters
