	P.N. Alekseev ITEP, Moscow, Russia
	Ions injector I-3 of the ITEP-TWAC accelerator complex consists of a buncher, two-gap accelerating cavity and a beam transport line. Laser ion source is used to generate ions for the injector. Possibility of application of the injector to dope semiconductor materials with variable energy ions is considered. Results of beam parameters optimization by numerical simulation to produce uniform distribution of particles density and required energy spread on the target are presented.

	New experimental results of obtaining accelerated deuterons in the small-sized diode with magnetic insulation are reported. The effective mode of ion acceleration to energies at 300 keV in the diode with a high voltage anode in order to initiate nuclear reactions D(d, n)3He is obtained with diode current ~0,5 kA and impulse duration ~1 mks in vacuum ~510^-2 Pa. Containing deuterons laser plasma was generated at the anode during TiD target laser irradiation with a wavelength of 1.06 microns and a power density of ~510¹⁴ W/m2. Accelerating voltage impulse was formed using Arkadyev–Marx 20 cascade impulse voltage generator with air insulation. Diode cathode covers the anode symmetrically. It is a hollow cylinder permanent magnet with induction on the axis ~0,4 T. Magnetic insulation in accelerating gap leads to suppression of the accelerated electrons current at level of 0.5 in relation to the total diode current. Used methods of accelerating diode ion current, accelerating impulse voltage and penetrating radiations characteristics measurements are described.

	The features of hydrogen nuclides extraction from vacuum-arc plasma and laser sources by electric field research results are presented in the report. Such sources can be used in accelerators injection systems and in neutron generators. These processes, found, are strongly influenced by electrostatic oscillations in the plasma boundary, which position continuously varies, in addition to the ions thermal motion. Such movement kinematics determined by the velocity field in plasma formation and its concentration reducing because of the ions extraction. On the basis of this model it shows that plasma boundary moves initially in the direction to the ejection electrode, then stops and begins quickly move back. An equation for the nuclides emission current density from hydrogen plasma surface for their quasiplanar extraction geometry is obtained.
