Analysis of laser wakefield particle acceleration data is a challenging task. Our approach combines and extends techniques from high performance scientific data management and visualization, enabling researchers to gain insight from extremely large, complex, time-varying laser wakefield accelerator simulation data. We extend histogram-based parallel coordinates which we use as visual information display and interface for guiding and performing data mining operations. We use multi-dimensional thresholding as vehicle for selecting particles of interest at a particular timepoint. We use FastBit, a state-of-the-art index/query system for data extraction and subsettingis of laser wakefield particle acceleration data is a challenging task.

The heightfield represents particle density from a VORPAL dataset of a laser wakefield acceleration. The spheres are individual particles whose velocity exceeds a certain threshold. Since we only had access to a single timestep of data, we randomly perturbed the heightfield and spheres to show we can handle time-varying datasets. T. Ize, SCI.
