In this Let’s Talk Exascale podcast, researchers from LBNL discuss how the WarpX project are developing an exascale application for plasma accelerator research. “The new breeds of virtual experiments that the WarpX team is developing are not possible with current technologies and will bring huge savings in research costs, according to the project’s summary information available on ECP’s website. The summary also states that more affordable research will lead to the design of a plasma-based collider, and even bigger savings by enabling the characterization of the accelerator before it is built.”
