Title: Exploring high-intensity and high-quality proton beams at IOTA

Zoom: Provided in weekly newsletter


Three key challenges in accelerator physics critical to the development of future colliders and radiation sources are increasing the beam intensity, phase space density and superior control of the particle distribution. For instance, medium-energy bright electron beams may be used to drive intense light sources.

I discuss my past work at the Cornell BNL ERL Test Accelerator (CBETA), which aims to generate multi-megawatt electron beams through energy recovery. On the other hand, intense proton beams are used in particle colliders, to drive spallation targets, etc. The beam current in these machines is limited by beam loss triggered by space-charge effects and collective instabilities. I describe my current research exploring beam dynamics in the large incoherent tune shift regime, using electron cooling of low energy proton beams.

Finally, I propose to extend my current work at the Integrable Optics Test Accelerator (IOTA) in Fermilab to study the interplay of space-charge with beam cooling, non-linear optics, and collective instabilities through the novel use of diagnostics, numerical models, and data-driven techniques.
