Abstract:

The method of energy dispersion in magnetic field is used to analyze the energy spread of the triple-pulse electron beam generated by the Dragon-II linear induction
accelerator. A sector magnet is applied for energy analysis of the electron beam, with a bending radius of 300 mm and a deflection angle of 90. For each pulse, the time-resolved and integral images of the electron position at the output port of beam-bending line are recorded by a streak camera and a CCD camera, respectively. Experimental results demonstrate an energy spread of less than ±2.0% for the electron pulses. The cavity voltage waveforms obtained by different detectors are also analyzed for comparison.
