Energy spectrum analysis for intense pulsed electron beam

Pulsed Electron-Beam Heating

A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs. time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time T is proportional to d , where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate...

Optical Transition Radiation (OTR) Measurements of an Intense Pulsed Electron Beam

By using the OTR angular distribution property [1], it is possible to extract the energy and the angular dispersion of several kinds of beam [2]. Recently, Le Sage et al. [3] succeeded in producing a transverse phase-space mapping of a 100 MeV electron beam by coupling an interferometric measurement and a ’’mask’’ technique. We present the first OTR time resolved angular distribution measuremen...

Energy Monitoring Device for Electron Beam Facilities

An easy-to-use and robust energy monitoring device has been developed for reliable detection of dayto-day small variations in the electron beam energy, a critical parameter for quality control and quality assurance in industrial radiation processing. It has potential for using on-line, thus providing real-time information. Its working principle is based on the measurement of currents, or charge...

Title of Dissertation : LONGITUDINAL DYNAMICS OF AN INTENSE ELECTRON BEAM

Title of Dissertation: LONGITUDINAL DYNAMICS OF AN INTENSE ELECTRON BEAM John Richardson Harris, Ph.D., 2005 Dissertation Directed By: Professor Patrick G. O'Shea, Department of Electrical and Computer Engineering The dynamics of charged particle beams are governed by the particles' thermal velocities, external focusing forces, and Coulomb forces. Beams in which Coulomb forces play the dominant...
