TIME-RESOLVED MEASUREMENT SYSTEM USING OPTICAL TRANSITION RADIATION FOR ELECTRON BEAM OF HIGH ENERGY AND HIGH CURRENT
The technology using Optical Transition Radiation (OTR) which is a main method for measuring the electron beam of high energy and high current has been developed for the past ten years. OTR characterized by the ultra-fast response, high resolution and capability of measuring both spatial and angular profiles of an electron beam. It also can measure the beam energy and divergence. A time-resolved measurement results of an electron beam produced by Linear Induction Accelerator (LIA) can provide much more detail information so that many problems about the beam transmission can be known well. Such a time-resolved measurement system has been developed recently in our lab and put into operation. It provides an on-line beam diagnostic method for a 18.5MeV、 2kA、 90ns(FWHM) electron pulse by Dragon I. The beam emittance and its variation during the 90ns pulse are obtained in 10ns time interval. The time-resolved results of about 2200π.mm.mrad have been obtained from Dragon I.
