Ion acceleration mechanism in mega-ampere gas-puff z-pinches

Publikováno v: New Journal of Physics, Vol 20, Iss 5, p 053064 (2018)

Acceleration of high energy ions was observed in z-pinches and dense plasma foci as early as the 1950s. Even though many theories have been suggested, the ion acceleration mechanism remains a source of controversy. Recently, the experiments on the GI

Publikováno v: Matter and Radiation at Extremes, Vol 9, Iss 2, Pp 027201-027201-10 (2024)

Directed x-rays produced in the interaction of sub-picosecond laser pulses of moderate relativistic intensity with plasma of near-critical density are investigated. Synchrotron-like (betatron) radiation occurs in the process of direct laser accelerat

Neutron production in cavity pressure acceleration of plasma objects

Publikováno v: AIP Advances, Vol 10, Iss 8, Pp 085206-085206-6 (2020)

The laser-induced Cavity Pressure Acceleration (CPA) scheme [S. Borodziuk et al., Appl. Phys. Lett. 95, 231501 (2009)] allows for effective transformation of the laser energy into the kinetic energy of plasma streams and dense plasma objects. It has

Scenario of a magnetic dynamo and magnetic reconnection in a plasma focus discharge

Autor: P. Kubes, M. Paduch, M. J. Sadowski, J. Cikhardt, D. Klir, J. Kravarik, R. Kwiatkowski, V. Munzar, K. Rezac, A. Szymaszek, K. Tomaszewski, E. Zielinska, M. Akel, B. Cikhardtova

Publikováno v: Matter and Radiation at Extremes, Vol 5, Iss 4, Pp 046401-046401-9 (2020)

The paper discusses a possible energy transformation that leads to the acceleration of fast ions and electrons. In plasma-focus discharges that occur during deuterium filling, which have a maximum current of about 1 MA, the accelerated deuterons prod

Ion acceleration and neutron production in hybrid gas-puff z-pinches on the GIT-12 and HAWK generators

Publikováno v: Matter and Radiation at Extremes, Vol 5, Iss 2, Pp 026401-026401-10 (2020)

Z-pinch experiments with a hybrid configuration of a deuterium gas puff have been carried out on the HAWK (NRL, Washington, DC) and GIT-12 (IHCE, Tomsk) pulsed power generators at 0.7 MA and 3 MA currents, respectively. On GIT-12, neutron yields reac
