The acceleration of hydrogen ions up to 35MeV is observed in the z-pinch experiments on the GIT-12 generator at a 3MA current and 0.6MV driving voltage. High ion energies are obtained with a novel configuration of a deuterium gas-puff z-pinch. In this configuration, a hollow cylindrical plasma shell is injected around an inner deuterium gas puff to form a homogeneous, uniformly conducting layer between electrodes at the initial phase of z-pinch implosion. The stable implosion at the velocity up to 650kms−1 is important to deliver more current onto the z-pinch axis. The ∼20ns pulses of high-energy photons, neutrons, electrons, and ions are observed. The average neutron yield is 2×1012. The ion emission is characterized by various diagnostic techniques. The neutron production efficiency of ∼108 neutrons per one Joule of the z-pinch energy was observed.
