Abstract

MA focused discharges are very intense, pulsed sources of ion cluster and superciuster beams with energy > 1 MeV/nucleon. Our experimental data refer to: (i) The mechanism of cluster formation and related plasma cooling processes. (ii) The mass/charge spectrum (1 ≤ m/z ≈ 1012 in A.U.). (iii) The anisotropy of the energy spectrum and of the emission intensity. (iv) The space and time structure of the source. (v) Beam focalization and neutralization. The experimental data have been obtained by operating the source at different levels of energy Wo = 6-25 kJ (Vo = 15-30 kV) of the fast capacitors bank which feeds the discharge. The inductive fields in the discharge pinch accelerate deuterium ions to energy values Ei ≈ 10 MeV. Beam focalization and neutralization is achieved with a pulsed-magnetic plasma lens on a 0.1 μs time scale. A Thomson spectrometer with nanosec periodic-or ramped-electric field is used for a time-resolved analysis of the beams.
