Abstract
A novel scheme to measure the longitudinal emittance and phase space profile in an electron storage ring by using correlations between time and the vertical coordinate, and between energy and the horizontal coordinate, is proposed. This longitudinal profile measurement scheme will help to demonstrate recent results of advanced studies for manipulating the longitudinal beam profile and for investigating beam instability in an electron storage ring.
Highlights
Transverse bunch crabbing using a two-frequency crab cavity scheme (Zholents, 2015; Huang et al, 2019) provides the optimal solution to produce short-pulse (1–10 ps full width at half-maximum) X-rays in a storage ring
Regardless of using a crab cavity, the distribution of the energy deviation = dp=p of a bunch can be projected in the x dimension at which horizontal dispersion x is large
We have described a novel scheme to measure the emittance and phase space profile in the longitudinal plane by using correlations between time and the vertical coordinate, and between energy and the horizontal coordinate
Summary
Transverse bunch crabbing using a two-frequency crab cavity scheme (Zholents, 2015; Huang et al, 2019) provides the optimal solution to produce short-pulse (1–10 ps full width at half-maximum) X-rays in a storage ring. Regardless of using a crab cavity, the distribution of the energy deviation = dp=p of a bunch can be projected in the x dimension at which horizontal dispersion x is large The resolution of this is limited by the ratio "x /x. All of these rings use the MBA concept. We examine the resolution of the measurement when wakefield data are included
