Final report for Integrated Simulations for a High Energy, High Power Energy Recovery Linac
- RadiaSoft, LLC, Boulder, CO (United States)
A next generation electron-ion collider is key for probing nuclear matter and understanding the structure of spin in the nucleus. All current electron-ion collider designs rely on energy recovery linacs (ERLs). The linac-ring configuration of an eRHIC collider under development at Brookhaven National Laboratory will use an ERL as the linac, while both the Brookhaven and Jefferson National Laboratory designs will use an ERL to drive a magnetized cooling system for the ion beams. All such designs will operate ERLs well beyond established parameters. The efficiency of an ERL depends sensitively on the beam quality, which will be strongly disrupted in a collider and may be difficult to operate with a magnetized electron beam. Perhaps more importantly, the threshold current for beam break-up instability is the current limit to the maximum beam power. Understanding how these effects will appear in an electron-ion collider is critical for designing the machine, as the limits to beam current can prevent the facilities from reaching their design luminosities. To understand these effects in detail with such complex machines requires fast,high-fidelity simulations. The resulting simulation tools could also be used to design a new kind of beam dump, which uses enhanced resistive wall losses to decelerate the final bunch before it reaches the beam dump.
