TL;DR: Through pit counting of carbon-ion tracks in CR39, it is shown that conversion efficiency of laser light to energetic carbon ions exceeds ~5% for these targets, which is above average for laser-accelerated multi-MeV targets.

TL;DR: The newest generation of Gas Cherenkov Detector (GCD-3) employed in Inertial Confinement Fusion experiments at the Omega Laser Facility has provided improved performance over previous generations, and is now being brought to the National Ignition Facility (NIF) to supplement the existing Gamma Reaction History (GRH-6m).

TL;DR: The gamma-to-electron magnetic spectrometer, having better than 5% energy resolution, is proposed to resolve γ-rays in the range of E(o) ± 20% in single shot, where E(O) is the central energy and is tunable from 2 to 25 MeV.

TL;DR: Test measurements of the PD-PMT at Atomic Weapons Establishment confirmed that design goals have been met and features such as onset of alpha heating, shock reverberations, and burn truncation due to dynamically evolving failure modes may become visible for the first time.
