WebOct 31, 2024 · 2.1 Experimental Setup. The swarm measurements were performed in a Pulsed Townsend setup. It consists mainly of a stainless steel vessel containing two Rogowski electrodes placed at an adjustable distance d from each other and across which a high voltage is applied such that a homogeneous electric field is created in the gap. Inside … WebThe pulsed-Townsend (PT) experiment is a well known swarm technique used to measure transport properties from a current in an external circuit, the analysis of which is based on the governing equation of continuity. In this paper, the Brambring representation (1964 Z. Phys. 179 532) of the equation of continuity often used to analyse the PT ...
WebThe Lorentz method is applied to the combined drift and diffusion of the electron stream in the Townsend experiment. The zeroth-order approximation is found to lead to the equation found by Townsend. It is shown how the next approximation is obtained. The same method is then applied to the drift of electrons in crossed electric and magnetic fields. It is found …
