Electron beam dynamics: Session-7
- Yuantao Ding (SLAC National Accelerator Laboratory)
The MAX IV bunch compressors consist of two achromatic arcs each where linearisation of longitudinal phase space is done with a sextupole in the centre of each achromat instead of a harmonic cavity. Although the initial design choice was a cost-saving solution, simulations and 10 years of experience demonstrate that arc compressors not only perform as well as a chicane compression system but...
One of the key barriers to the generation of free-electron laser (FEL) pulses that are fully longitudinally coherent is the microbunching instability. Numerous methods for suppressing this instability have been studied, and recent investigations at the FERMI FEL have demonstrated that the transverse beam optics can play an important role in achieving this mitigation. Experimental and...
Steady-State Micro-Bunching (SSMB) was proposed by Ratner and Chao in 2010 to generate high-power short-wavelength coherent radiation in an electron storage ring. To advance the SSMB development, an SSMB taskforce was established in Tsinghua University since 2017, in collaboration with several institutes around the world. In this talk, the recent progress achieved by the SSMB collaboration...
Plasma and beam physics are usually considered as classical physics disciplines with quantum effects featuring only rarely. In particular, free electron lasers (FELs) even in the Angstrom regime (developed recently and being upgraded towards even shorter wavelengths) are well described by classical mechanics and electrodynamics. There is, however, a quantum effect that can influence the...
