(U) Introducing HEDONIST- A Low Explosive Mass Experiment That Attains Very High Pressures
ORAL
Abstract
The proton radiography facility at LANL offers unique experimental capabilities,
particularly the planned Pu@pRad line. Pu@pRad limitations however preclude the usage
of large quantities of high explosives. We present the hydrocode analysis of a small-scale
system (under 30g TNT equivalent) capable of reaching pressures in excess of 2 Mbar.
This system utilizes a novel multipoint initiation system to establish converging
detonation waves which deliver a strong shock wave onto a sample cell. HEDONIST has
been designed to present a low areal density to the pRad beam thereby providing ample
signal-to-noise ratio to discern shock waves in sample cell materials from other shocks
present. Results from the first two pRad experiments and the comparison to hydrocode
simulations will be discussed.
