Extended Data Fig. 2: Simulated longitudinal quantities along the accelerator.
From: Realization of a multi-turn energy recovery accelerator

Visualization of the centroid momentum, \(\bar p\), the momentum spread, σδ, and the bunch length, σt, as function of the location, s, starting after the injector LINAC. The bunch length is changing due to different velocities of the electrons and due to different path lengths of the electrons caused by the longitudinal dispersion. The effect of the longitudinal dispersion is implemented in the simulations by elements of zero length at the end of the corresponding sections.
