Abstract

Abstract

The control of the electron beam in an intense current linear induction accelerator(LIA)is very important. The center position of the electron beam and the beam profile are two important parameters which should be measured accurately. The setup of a time-resolved measurement system and a data processing method for determining the beam center position are introduced for the purpose of obtaining Dragon-Ⅰ electron beam trajectory including beam profile.The actual results show that the centroid position error can be controlled in one to two pixels. The time-resolved beam centroid trajectory of Dragon-Ⅰ(18.5 MeV, 2 kA, 90 ns) is obtained recently in 10 ns interval, 3 ns exposure time with a multi-frame gated camera. The results show that the screw movement of the electron beam is mainly limit
- intense current electron beam,
- beam centroid,
- linear induction accelerator,
- high speed multi-frame gated camera
