Hypervelocity Jets

Hypervelocity Jets

The impact of Hypervelocity Jets at ~100 km/s generates extremely high pressure shocks for investigating astrophysical phenomena and energy efficient x-ray generation for nuclear fusion.

We develop devices for generating Hypervelocity Jets and investigate MIMS (Metastable Innershell Molecular State), the ultra-energetic molecule created by the impact of the jets.

Explosive-Driven Hypervelocity Jet Generator

Schematic of the demonstrator built in collaboration with the Los Alamos National Lab.


PWL = plane wave lens; HE = high explosive PBX-9501; MP = metal piston; CP = cap plate; D = diaphragm; ST = the evacuated shock-tube; PDV = photon Doppler velocimetry probes (2); MI = microwave interferometer.

The confinement was transparent PMMA. The distance between the diaphragm and the left of the cap plate is 190.5 mm.
