Description
Investigation into laser-based manipulations on the longitudinal phase-space of bunches has been conducted experimentally at Fermilab’s linear accelerator. We continue to explore the advantages of using such a system in the application of beam-loss reduction. Particle bunches exiting the RFQ have been bunched to roughly 201 MHz or 4 ns FWHM. These particles then enter a small drift prior to the first acceleration module. During this drift, simulation shows that it is feasible to reduce the number of large change-of-energy particles via longitudinal scrapes, thus leading to a theoretical reduction in losses further downstream. Utilizing experimental data, we model laser and H⁻ interactions replicating those found within the Laser Notcher interaction cavity and further effects down the linac. We propose a method using Laser-Notcher-like systems as a solution to mitigate losses in future accelerating systems.
