Beam Stacking Experiment at a Fixed Field Alternating Gradient Accelerator

Autor: Uesugi, T., Ishi, Y., Kuriyama, Y., Mori, Y., Jolly, C., Kelliher, D. J., Lagrange, J. -B., Letchford, A. P., Machida, S., de Boer, D. W. Poshuma, Rogers, C. T., Yamakawa, E., Topp-Mugglestone, M.

A key challenge in particle accelerators is to achieve high peak intensity. Space charge is particularly strong at lower energy such as during injection and typically limits achievable peak intensity. The beam stacking technique can overcome this lim

Accelerated muon beams have been considered for next-generation studies of high-energy lepton-antilepton collisions and neutrino oscillations. However, high-brightness muon beams have not yet been produced. The main challenge for muon acceleration an
