Common Component Architecture for Electron Cloud Accelerator Simulations
Electron cloud generation is one of the most scientifically important effects relating to the dynamics of particle beams. The build up of an electron cloud is a potentially limiting factor in the perÂformance of high-intensity electron and proton machines. However, electron cloud simulation presents computational challenges because the number of particles is large and because efficient code coupling of beam physics with electron cloud generation code is required. This project will develop technology for composing electron cloud simulations on leadership-class supercomputing hardware. Phase I demonstrated an electron cloud simulation using TxPhysics and Synergia2 accelerator code components within the Common Component Architecture framework. In addition, a single processor and multiÂprocessor performance model was developed to characterize the behavior of the space charge kick calculation in Synergia2. Phase II will create new accelerator components for use on leadership-class supercomputers. Commercial Applications and other Benefits as described by the awardee: The modeling of electron cloud effects is important for high energy accelerators and the Fermilab main injector. By focusing on the development and distribution infrastructure within the computational science community, a unique niche within the much larger software engineering market would be addressed .
