The characteristics of pulsed electron beam generated by multiplate pseudospark chamber (MPC) on the basis of field escalation effects have been described in this paper.
The process of vacuum electron beam welding for rear-axle housing semiaxle of coach was introduced and the major problems in the process of welding was analysed.
The incredibly small beam then hits the specimen composed of different elements and densities of materials, thus scattering the electrons in different ways thereby imprinting an image on the transmitted electron beam.
The next lenses, the objective and a series of four projector lenses, are used to resolve and magnify the miniscule image imprinted into the electron beam up to a width of a few centimeters.
The purpose of having two systems is that the phosphorescent screen and camera is used to ensure that the electron beam and magnetic lenses are set up properly, as an incorrectly focused beam could damage the sensitive CMOS camera.
