Study of transfer efficiency in a screw pinch plasma
Abstract
A screwpinch for UV generation and possible FAIR plasma stripper applications was designed based on a previous development. The intention was to increase the applicable voltage and as a result the electron density. Research was conducted into the transfer efficiency for plasma generation providing preliminary values up to 66%. The device operates at a frequency of approximate 14 kHz and is characterised by a capacity of 34 μF , a thyratron switch with a maximum current rise time of 5 MA / μs as well as a variable set of up to 5 planar coils with diameters of 172 and 208 mm . A cylindrical volume of 4 l can thusly be ignited within the region of 5 .10-3 to 1 mbar with an applied voltage of 6 to 13 kV , resulting in peak electron densities of 4 .1016 electrons per cm3 .
