Generation and measurement of subpicosecond electron beam pulses

Abstract
The generation and measurement of subpicosecond electron beam pulses by the transverse-longitudinal combination gate system is described. The temporal property of the pulse gate is analyzed with the help of the longitudinal emittance diagram. Close agreement has been obtained between the calculated pulse width and the observed one which was measured by the Lissajous's figure method. A beam pulse of 0.2 ps (FWHM) was produced.
