HED-Melt: A coupled framework for modeling high-energy-density conditions in accelerators

The high-brightness beams used by modern light sources and accelerators present a new challenge for machince protection. These beams, through impacts with beam intercepting components such as collimators, may generate high-energy-density (HED) conditions capable of causing significant damage to machine components. One significant issue in studying these dynamics is that lack of simulation tools which capture all of the physics present. Particle tracking and particle-matter interaction codes are widely used in accelerator design but the is not significant interfacing between the two and few codes are available to simulate the melting and vaporization seen in some beam strikes. HED-Melt (High Energy Density Modeling of ELectron beam impacts Toolkit) is a framework of coupling three physics codes, elegant, fluka, and flash to model the effects of HED conditions in various accelerators components. The toolkit automatically interfaces between the three codes to run a full-physics simulation of HED conditions for a user-defined machine lattice.
