WebMay 17, 1993 · Chicane and wiggler based bunch compressors for future linear colliders. In this paper, we discuss bunch compressors for future linear colliders. In the past, the bunch compression optics has been based upon achromatic cells using strong sextupoles to correct the dispersive and betatron chromaticity. To preserve the very small emittances ...
A magnetic chicane also called a bunch compressor helps form dense bunches of electrons in a free-electron laser. A magnetic chicane makes electrons detour slightly from their otherwise straight bath, and in that way is similar to a chicane on a road. A magnetic chicane consists of four dipole magnets, giving electrons at the beginning of a bunch a longer path than electrons at the end of the bunch, thereby allowing the laging electrons to catc… WebNovel bunch compressor chicane: The five-bend chicane Donish Z.

WebNov 16, 2024 · A harmonic cavity, usually an X-band, is used to linearize the bunch compression process and compensate for the second-order compression effects . Similarly, a third harmonic cavity is used as the linearizer upstream of the first bunch compressor chicane (BC1) in the SC linac-based high-repetition-rate FEL facilities. iat find an agentWebAs an example, the BSY 51, 52 B2 dipoles are shown in figure 1. These are C-type magnets whose length just matches the 2 nd bunch compressor chicane magnet. The length of the chicane dipoles could be adjusted to match other existing magnets, and in general a longer magnet is more favorable for minimizing synchrotron radiation related emittance growth. iash university of edinburghWebdescription of our methodology which can be used as a general guideline for other bunch compressor designs.
