摘要A novel model for the inter-bunch interference in a bunch train is presented where a train of electron bunches passing through a bending or undulator magnetic field is considered as a moving multi-slit diffraction array from which multi beams of coherent radiation emitted with definite phase difference. Based on this model,interference among multi-beams of coherent synchrotron radiation emitted from consecutive bunches accelerated by a 30 MeV RF-Linac at BFEL is analyzed and numerically calculated. From the discussions it is shown that: 1. Rapidly oscillating radiation enhancement due to inter-bunch interference is overlapped on the single bunch power spectrum; 2. Such radiation enhancement consists of series of spectrum lines corresponding to harmonics of the fundamental of RF-Linac; 3. Main maximum positions are determined by the "diffraction condition"; 4. Intensity enhancement is about as high as the number of bunches in a macropulse; 5. The axially measured radiation frequency is lower than the off axis one. Experimental design to measure interference from separate bunches at the BFEL Linac with the developed mm-wave Michelson interferometer is presented.
