Description
Emittance exchange (EEX) is an attractive approach for generating high-frequency bunch trains from transverse modulations. Ongoing efforts aim to explore the limits of longitudinal modulations achievable with EEX beamlines and methods for enhancing radiation brightness for a given beam. One project investigates the generation of nanometer-scale longitudinal modulation using a transmission electron microscope (TEM) grid combined with a quadrupole demagnifier that controls the period of the transverse density modulation. Another project explores the feasibility of generating a sawtooth correlation—known to maximize radiation brightness from a single bunch--using transverse wigglers. We present the goals and status of these projects. This includes the design of an EEX beamline compatible with nanometer-scale modulation and a transverse wiggler system for producing sawtooth correlations.
