H7.00001: Synergia: a new platform for beam dynamics with multiple bunch interactions Invited Speaker: James Amundson Synergia is a dynamic platform for the simulation of beam dynamics scales from simple simulations on the desktop to complex simulations requiring massively parallel computers. Synergia has the capability to simulate collective effects in both single bunches and trains of bunches, including space charge with in a bunch and intra- as well as inter-bunch wakefields. We have recently extended Synergia to simulate dual overlapping trains of bunches in order to study slip-stacking the Fermilab Recycler storage ring. I will present an overview of Synergia along with recent applications to the Recycler. [Preview Abstract] |

H7.00002: High Resolution Beam Modeling and Optimization with IMPACT Invited Speaker: Ji Qiang The LCLS-II, a new BES x-ray FEL facility at SLAC, is being designed using the IMPACT simulation code which includes a full model for the electron beam transport with 3-D space charge effects as well as IntraBeam Scattering and Coherent Synchrotron Radiation. A 22 parameter optimization is being used to find injector and linac configurations that achieve the design specifications. The detailed physics models in IMPACT are being benchmarked against experiments at LCLS. [Preview Abstract] |

H7.00003: WARP-X: a new exascale computing platform for Beam-Plasma Simulations Invited Speaker: Jean-Luc Vay Particle accelerators are a vital part of the DOE-supported infrastructure of discovery science and university- and private-sector applications, and have a broad range of benefits to industry, security, energy, the environment and medicine. To take full advantage of their societal benefits, however, we need game-changing improvements in the size and cost of accelerators. Plasma-based particle accelerators stand apart in their potential for these improvements. Turning this from a promising technology into a mainstream scientific tool depends critically on high-performance, high-fidelity modeling of complex processes that develop over a wide range of space and time scales. As part of DOE’s Exascale Computing Project, a team from Lawrence Berkeley National Laboratory, in collaboration with teams from SLAC National Accelerator Laboratory and Lawrence Livermore National Laboratory, will develop a new powerful plasma accelerator simulation tool. The new software will harness the power of future exascale supercomputers for the exploration of outstanding questions in the physics of acceleration and transport of particle beams in chains of plasma channels. This will benefit the ultimate goal of compact and affordable high-energy physics colliders, and many spinoff applications of plasma accelerators along the way. [Preview Abstract] |
