High resolving power spectrometer for beam analysis

A system designed to analyze the high energy, closely spaced bunches from individual RF pulses is described. The spectrometer is a compact, double-focusing QBQ design, assuring a flexibility for spatially separating all of the bunches along the focal plane with minimal transverse kicks and bending angle for differing input conditions. The optics and the hardware that is proposed to measure emittance, energy, energy spread and bunch length for each bunch in an RF pulse train for small bunch separations are discussed.
