Acceleration of protons and deuterons up to 35 MeV and generation of 1013 neutrons in a megaampere deuterium gas-puff z-pinch

Abstract: The acceleration of hydrogen ions up to 35 MeV is observed in the z-pinch experiments on the GIT-12 generator at a 3 MA current and 0.6 MV 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 650 km s … Show more

“…Experiments were carried out in a configuration that provided a uniform current sheath of radius 14-16 cm when a high-voltage pulse was applied to the load (figure 1). This configuration, previously used in experiments with hybrid deuterium gas-puffs [7,21,22] was produce using a plasma shell. The plasma shell, which consisted of hydrogen and carbon ions, was generated by 48 cable guns arranged in a circle of radius 17.5 cm (see [23] for details).…”

“…The compression of plasmas by self-magnetic fields, known as the pinch effect, makes it possible to study high-density, hightemperature plasmas under laboratory conditions. To produce such plasmas, fast Z-pinches [1,2] are widely used as powerful sources of soft x-rays and as possible drivers for inertial confinement fusion [3][4][5][6][7].…”

“…Assume that the temperature and density are perturbed in azimuth, that is: (12) where T 1 (t, ϕ) and ρ 1 (t, ϕ) are small temperature and density perturbations, respectively. (Throughout the text below, we will denote the unperturbed values of the functions by the subscript '0', and the subscript '1' will denote small perturbations).…”

“…The electromagnetic compression of a material object carrying an electric current, which occurs in Z pinches [1][2][3][4][5], is one of the most efficient ways to obtain a dense high-temperature plasma. Currently, Z pinches are widely studied both as powerful sources of soft x-rays [1,[6][7][8][9] and as possible drivers for inertial confinement fusion [2,3,5,[10][11][12]. For instance, in the research carried out under the Magnetized Liner Inertial Fusion (MagLIF) project [5,[13][14][15], it is proposed to compress a deuterium-tritium (DT) mixture, initially heated by * Author to whom any correspondence should be addressed.…”

“…Different loads such as deuterium gas-puff with on-axis wires, double gas-puffs, and metal-puffs were used. Progress has been made in optimizing load parameters for a high K-shell radiation yield and ensuring stable implosion at microsecond times [2][3][4][5][6].…”
