CMA-Unfold A Covariance Matrix Adaptation unfolding algorithm for stacked calorimeter detectors
G. Fauvel, A. Arefiev, M. Manuel +3
Stacking calorimeters also refered as bremsstrahlung cannons widely used in inertial confinement fusion and ultra-intense laser plasma experiments have become essential diagnostics…
Investigation of Laser Plasma Instabilities driven by Coupled High-Power Laser Beams in Magnetized Underdense Plasmas
C. L. C. Lacoste, D. Oportus, J. Béard +10
Stimulated Brillouin and Raman scattering (SBS and SRS) are instabilities that affect the propagation of high-power lasers in plasmas. The latter is further affected by Cross-Talk…
Collimated -ray emission enabled by efficient direct laser acceleration
Kavin Tangtartharakul, Gaetan Fauvel, Talia Meir +5
We investigate the mechanisms responsible for single-lobed versus double-lobed angular distributions of emitted -rays in laser-irradiated plasmas, focusing on how direct laser…
Compact in-vacuum gamma-ray spectrometer for high-repetition rate PW-class laser-matter interaction
G. Fauvel, K. Tangtartharakul, A. Arefiev +10
With the advent of high repetition rate laser facilities, novel diagnostic tools compatible with these advanced specifications are required. This paper presents the design of an ac…
Speed of sound in methane under conditions of planetary interiors
Thomas G. White, Hannah Poole, Emma E. McBride +32
We present direct observations of acoustic waves in warm dense matter. We analyze wave-number- and energy-resolved x-ray spectra taken from warm dense methane created by laser heat…
