Experimental investigation on sheet electron beam transport with Electron Beam Measuring and Analyzing System developed in IECAS
Recently, a set of instrument named Electron Beam Measuring and Analyzing System (EBMAS) has being built in Institute of Electronics, Chinese Academy of Sciences (IECAS), which can be used to measure the dynamic parameters for the high power electron beam during its formation and transport for microwave vacuum electron devices. In this paper, the EBMAS with its measurement of cross section, current density, energy dispersion, and its three dimensional trajectory with data acquisition and processing system are introduced for the high power electron beam. Then, the instrument is used to measure and analyze the sheet electron beam transport and theirs Diocotron instabilities for the W-band sheet beam klystron developed in IECAS, the thorough experiment results are presented, and good agreement are obtained for the experiment and simulation results.
