IPAC’23 / STUDENT POSTER SESSION GUIDE 35 Student Poster Session SUPM061 Electron Microbunching using the Amplified Optical Stochastic Cooling Mechanism Austin Dick , Philippe Piot (Northern Illinois University). Optical Stochastic Cooling (OSC) is a feedback beam cooling technique that uses radiation pro- duced by a beam to correct particles’ own momentum deviation. This system is made up of two undulator magnets, the pickup and kicker, separated by a bypass chicane that introduces a momentum-dependent path length. The beam produces radiation in the pickup and arrives in the kicker with a delay relative to its momentum, where it is coupled with the undulator radiation, receiving a corrective kick. The undulator radiation can be amplified to increase the strength of the corrective kick; this is done using an optical amplifier. The optical amplifier is driven by a pump laser which can be used to selectively amplify temporal slices of the undula- tor radiation. In this paper, we propose a method to use the amplified-OSC mechanism to cre- ate micro-bunches within the beam and study the performance of this multi-bunch-formation mechanism by considering diffusive effects and gain of the amplifier. SUPM062 Simulations of Radiation Reaction in Inverse Compton Sources Elizabeth Breen , Emerson Rogers, Erik Johnson, Balsa Terzic (Old Dominion University), Geoffrey Krafft (Thomas Jefferson National Accelerator Facility). The effect of radiation reaction is often negligible in inverse Compton scattering. However, in the nonlinear Compton regime, at high laser fields and high electron beam energies where electron recoil must be properly accounted for, there is experimental data which demonstrates the onset of radiation reaction * . We model the radiation reaction as a series of emissions from individual electrons with decreasing energy. This allows us to use the code we previously de- veloped for simulating single-emission inverse Compton scattering events ** . We use the new code to simulate the experiment reported in Cole et al. 2018, and to compare it to other models of radiation reaction. SUPM063 Optimizing the discovery of underlying nonlinear beam dynamics and moment evolution Liam Pocher , Irving Haber, Tom Antonsen (University of Maryland), Patrick O’Shea (University Mary- land). One of the Grand Challenges in beam physics relates to the use of virtual particle accelerators for beam prediction and optimization. Useful virtual accelerators rely on efficient and effective methodologies grounded in theory, simulation, and experiment. This work extends the appli- cation of the Sparse Identification of Nonlinear Dynamical systems (SINDy) algorithm, which we have previously presented at the North American Particle Accelerator Conference. The SIN- Dy methodology promises to simplify the optimization of accelerator design and commission-
