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

These current horns are formed after bunch compression due to non-linear correlations in the longitudinal phase space and the higher order optics of the compressor. It has been suggested that this higher order … high422和high444

Web12 de nov. de 2024 · WP3, high charge-Low Current: 200 pC charge in 400 fs RMS bunch length, which turns into 0.07 kA RMS current, with and without the longitudinal bunch compression in the magnetic chicane, to serve both the SASE-FEL, with peak current I p e a k = 2 kA, and the Compton and THz sources in the high flux operation scheme. Webbrightness is preserved at the injector level under acceleration and bunch- length compression. The importance of electron- beam brightness for linac -driven high -gain FELs is underlined by the characteristic FEL parameter U, through which most of the one -dimensional ( 1D ) FEL dynamics can be depicted [4] .
