AbstractProton ion acceleration via laser-generated plasma is investigated at relatively low laser pulse intensity, on the order of 1010 W/cm2. Time-of-flight technique is employed to measure the ion energy and the relative yield. An ion collector and an ion energy analyzer are used with this aim and to distinguish the number of charge states of the produced ions. The kinetic energy and the emission yield are measured through a consolidated theory, which assumes that the ion emission follows the Coulomb-Boltzmann-Shifted function. The proton stream is generated by thin and thick hydrogenated targets and it is dependent on the free electron states, which increase the laser absorption coefficient and the ion acceleration. The maximum proton energy, of about 200 eV, and the maximum proton amount can be obtained with thick metallic hydrogenated materials, such as the titanium hydrate TiH2.

The project ITEP-TWAC (Tera Watt Accumulator) being in progress at ITEP (Moscow) requires He-like ions for non-Liouvillean injection into the storage ring to accumulate ≈2·1013 particles with medium masses up to 59Co25+. Powerful lasers were found to be the best choice for those ions production. This work presents the experimental results of highly charge ion generation in plasmas produced by the second harmonic of Nd-glass laser facility with a total energy E ≤ 50 J and pulse duration of about 2.5 ns at GPI (Moscow). Ti and Ta targets were under investigation. An electrostatic ion energy analyzer and an ion charge collector were used to measure the ion charge state spectra at a 3-m distance from the targets. 5·107 He-like Ti ions per cm2 within 1 μs pulse as well as 107 Ta+41 per cm2 within 0.8 μs were observed.

This paper presents a set of complementary corpuscular diagnostics applied in experiments for investigation of laser-produced plasma as a source of ions. The measuring possibilities and methods for processing experimental data of a cylindrical electrostatic ion energy analyzer, a Thomson parabola ion analyzer, various types of electrostatic probes, a detector of neutral atom fluxes, as well as methods for visualization of ion emission areas are discussed. Special attention was focused on the ion-induced secondary electron emission problem and its influence on the accuracy of the measurements.
