	Generalized longitudinal strong focusing (GLSF), a ring-based beam manipulation technique, has been proposed to generate steady-state, nanometer-long electron bunches in laser-driven storage rings. Coherent EUV radiation can thus be produced with greatly enhanced power and photon flux, benefiting a wide range of scientific and industrial communities. The GLSF mechanism invokes precise transverse-longitudinal coupling dynamics and exploits the ultralow vertical beam emittance. In a GLSF ring, kW-level coherent EUV radiation is attainable.

MOPB039	Low-Alpha Storage Ring Design for Steady-State Microbunching to Generate EUV Radiation	88
	Z. Pan, A. Chao, X.J. Deng, W.-H. Huang, Z.Z. Li, C.-X. Tang TUB, Beijing, People’s Republic of China
	A new concept is proposed for minimizing the longitudinal emittance of a low momentum compaction factor (low-alpha) storage ring which has the capability to stably store sub-femtosecond electron bunches for the first time. This storage ring is designed for Steady-State microbunching (SSMB) to generate kW level average power EUV radiation. The proposed design approach can be applied to any quasi-isochronous storage rings to yield very high radiation power due to longitudinal coherence of the radiation. We obtain an optimal lattice design by minimizing global and local momentum compaction factors simultaneously and the result of single-particle tracking shows that the electron beam with equilibrium rms bunch length of about 40 nm can be stored in this ring. Nonlinear dynamics is studied for this lattice.

A new concept is proposed for minimizing the longitudinal emittance of a low momentum compaction factor (low-alpha) storage ring which has the capability to stably store sub-femtosecond electron bunches for the first time. This storage ring is designed for Steady-State microbunching (SSMB) to generate kW level average power EUV radiation. The proposed design approach can be applied to any quasi-isochronous storage rings to yield very high radiation power due to longitudinal coherence of the radiation. We obtain an optimal lattice design by minimizing global and local momentum compaction factors simultaneously and the result of single-particle tracking shows that the electron beam with equilibrium rms bunch length of about 40 nm can be stored in this ring. Nonlinear dynamics is studied for this lattice.
