MeV x-ray sources from dual compound parabolic concentrator targets

ORAL

Abstract

Experiments using the NIF Advanced Radiographic Capability (ARC) laser and compound parabolic concentrator (CPC) cone targets1 have demonstrated >10x enhancement in coupling to relativistic electrons and MeV photons, compared to flat targets. To generate multiple x-ray bursts, we are investigating using dual CPC cone targets with nanosecond delays between the cone interactions. Target features to mitigate the degradation of the second, delayed cone source have been tested, including different shielding and spatial configurations. The experimental results of this campaign will be presented, as well as multi-stage hydro and PIC simulation studies of the delayed cone interaction.
