Multi-Probe Radiography: For 2035 and Beyond

The Multi-Probe Radiography Project is investigating the use of multiple species of probe beams to provide more information from a radiography. Contextual radiographic, source, and measurements information is being provided through a series of four workshops at Los Alamos National Laboratory. The third workshop on Accelerator and Pulsed Power Technology is summarized in this report. The state of the large NNSA facilities such as Scorpius, DARHT, pRad, and Cygnus are presented. Future enhancements and innovative upgrades are also discussed.

Mitigation and characterization of crosstalk between laser-driven radiography sources

Radiography with multiple probe species offers the potential to extract additional information about a given object as compared to radiography with a single probe species. Notably, the flexibility for high-power, short-pulse lasers to accelerate a variety of particle species makes laser-driven sources an attractive option to achieve multi-probe radiography. However, crosstalk produced by each of laser-driven source may be responsible for substantial backgrounds on detectors, becoming a significant barrier to achieving simultaneous radiography. In this work, we describe measurements of and mitigation strategies against crosstalk between laser-driven radiography sources in experiments at the OMEGA EP laser.
