[en] Results of the study on the superdense plasma bunches detected in a low-inductive spark being one of the modifications of pinched discharges are presented. Their microscopic dimensions (approximately 10^-₃ cm) are a peculiar feature of plasma bunches, due to which they are called plasma points (PP). Peculiarities of multicharged ion emission with charges up to Z=25 from high temperature PP are studied. Present theoretical ideas on the nature of PP are analyzed. Specific features of PP decay are investigated. Study on the energy distributions of emitted ions has revealed monotonous increase of maximal energies of scattering at the growth of the element mass. The maximal rate of scattering decreased respectively. Energies of ion scattering increase with charge growth, the number of emitted ions drops in this case. The maximal energy of detected ions attains approximately 200 keV, while mean energy of scattering of plasma bunch is about 15 keV. Carbon nuclei, eleven-charge aluminium ions, sixteen-charge iron ions (maximal charge) were detected at scattering of plasma bunch

[en] It is reported about producing an intense beam of cluster carbon ions under effect of pulse CO₂-laser on a pure carbon target. Based on the investigations conducted a possibility of producing intense beams of cluster and molecular ions of various elements and compounds is discussed

[en] Consideration is given to results of investigation of elective extraction of ions by pulse electric fields from the surface of plasma, moving with ≥10⁴ m/s velocity under conditions of miniature accelerating diodes. Mathematical model of expansion of plasma bunch, formed by laser pulse (E_las<1 J) in quasicylindrical diode system is analyzed. Possibilities of increasing current of extracted ions with the use of phenomenon of magnetic insulation of electrons and diode systems with transparent anode are considered. The structures of developed small accelerating tubes for neutron pulse generation are presented. 10 refs., 11 figs., 1 tab

[en] Mechanisms of recombination process course at the initial stage of flare formation are detected according to the characteristics of laser plasma separation products. A possibility to control reconbination due to change in life time of the plasma is shown. The essential role of the recharging process of 'proper' and desorbed from the surface atoms when forming charged, angular and spacial distributions of laser plasma particles is pointed out

[en] Some results obtained at the development of ion laser source for cyclotrons with plasma extension along the magnetic field lines are presented. Special properties of ion extraction from laser plasma under B conditions, the effect of longtudinal B on charge spectrum of laser plasma and quantitative characteristics of plasma ion component are investigated. Sup(48)Tisup(12+), sup(52)Crsup(13+) were accelerated using CO₂ laser as a radiation source, and sup(12)Csup(3+) and sup(7)Lisup(2+) accelerated ion beams with 50 and 100 nA average current were obtained in the case of using LTI-4 laser. The ways of futher optimization of laser source for cyclotrons are discussed
