Web11 de set. de 2024 · For example, the beam with 0.157 mm bunch length, has acquired a compression factor of 7. While the transverse emittance of the “green circle” beam is only 1.605 μ. Conclusion. In conclusion, a brake-applied velocity bunching with a lower gradient is proposed for generating the high brightness electron beam. Weband CðsÞ¼½1−hR56ðsÞ −1 is the bunch compression factor, and h is the initial chirp of the beam (assuming z>0 for the bunch head). To quantify the microbunching, we define the amplification gain as modular ratio of bunching factors G f≡ bðk;s fÞ b0ðk;0Þ 1; ð7Þ where s f is denoted the exit location of a beam line. When
