A new method of determining H by means of the discharge from the Wehnelt cathode by Lars Alvin Welo Download PDF EPUB FB2

A mercury vapor lamp comprising a vessel adapted to provide a discharge path defined by the walls of said vessel, a Wehnelt type cathode and a co-operating electrode disposed at opposite ends of said path, a filling of inert gas and mercury vapor, the normal electron emission of said cathode and the pressure of inert gas being adapted to start.

The argon temperature and the emission intensity in the hollow cathode discharge were measured. We measured the line profiles of the 1sp8 transition in argon, using a single-frequency diode laser.

Radial distributions of He +, He + 2 and Kr + were measured in a hollow cathode discharge in He and in He-Kr mixtures using a mass spectrometer. The dimensions of the discharge were similar to those used in He-Kr + hollow cathode discharge lasers.

From the ion densities the electron density was by: 1. He chose a Wehnelt cathode, whose energy he could control, to produce electrons that ionized the gas under investigation. This approach had several advantages over the gas discharge method of ionization: Ions formed in this manner had a smaller energy spread Author: Michael A.

Laser oscillation in He−Zn, Ne−Cd, Xe−Cd and Ar−Cd mixtures has also been by: Using this method, Thomson found values of v of the order of × to × meters per second (about one tenth the velocity of light), and from to × coulombs / kilogram for the ratio of charge to mass for cathode ray particles.

The length of the cathode fall was observed to be very insensitive to all the macroscopic discharge parameters. A nearly constant value was found for the cathode fall length, which corresponds to about 22% of the cathode radius. 1 Introduction The hollow cathode glow discharge is a good source of metal atoms and ions, which has been used in the.

Where the cross-sectional area of the flow is constant, as in pressure conduit, the sudden-injection method may be used to determine the velocity of flow; discharge can then be computed by using that velocity and the known cross-sectional area.
