MOPR035 | Electron Lens for the Fermilab Integrable Optics Test Accelerator | 170 |
|
||
Funding: Fermilab is operated by Fermi Research Alliance, LLC, under Contract DE-AC02-07CH11359 with the US Department of Energy. The Integrable Optics Test Accelerator (IOTA) is a research machine currently being designed and built at Fermilab. The research program includes the study of nonlinear integrable lattices, beam dynamics with self fields, and optical stochastic cooling. One section of the ring will contain an electron lens, a low-energy magnetized electron beam overlapping with the circulating beam. The electron lens can work as a nonlinear element, as an electron cooler, or as a space-charge compensator. We describe the physical principles, experiment design, and hardware implementation plans for the IOTA electron lens. |

Head-Tail Modes With Strong Space Charge: Theory and Simulations | |
|
||
Low and medium energy hadron circular machines are operating at a condition of the strong space charge, i.e. with the space charge tune shift much higher than the synchrotron tune. Theory of transverse instabilities developed by the author for such cases was recently checked in multiparticle tracking with the Synergia code, and a good agreement was demonstrated both for the modes structure and Landau damping rates. Main aspects of the theory will be reminded and the comparison results be demonstrated. | ||
