Title: Modeling High-Energy-Density Conditions in Accelerators

Speaker: Austin Jacob (AJ) Dick

Time: Thursday, February 27 at 4PM ET/3PM CST

Abstract: The high-brightness beams being produced in current and future accelerators present new machine protection concerns with the potential for high-energy-density conditions (>100 J/mm^3) in beam-intercepting components.  We present a method for coupling particle dynamics, particle-matter interaction, and hydrodynamics codes to model the effects of high-intensity electron beams in APS-U and other accelerators. These codes, elegant, FLUKA, and FLASH respectively, are used to simulate the dynamics of an electron beam and collimator during a full beam loss in the APS-U storage ring. Starting with a circulating beam in elegant, the rf system is muted and the beam gradually loses energy before colliding with a horizontal collimator.  The interaction and thermodynamic evolution of the collimator material are then modeled in FLUKA and FLASH before the surviving beam distribution is returned to elegant. This coupled framework is used to study damage mitigation techniques for beam-collimator interactions and can also be used to examine the generation and absorption of synchrotron radiation within the vacuum beam chambers.
