TL;DR: A streaked optical pyrometer that measures the self-emission of laser-driven shocks simultaneously with a velocity interferometer system for any reflector (VISAR) to obtain the temporally and spatially resolved temperatures of approximately megabar shocks driven by the OMEGA laser.

Development and characterization of a pair of 30–40 ps x‐ray framing cameras
TL;DR: In this paper, two slightly different high-speed framing cameras for use on NOVA and OMEGA upgrade were constructed based on the gating of a microchannel plate, with one detector having a pore length to diameter ratio half that of the other.

TL;DR: In this paper, a pinhole detector was used to measure the distribution of neutrons passing through the pinhole, which is an important diagnostic tool for inertial fusion studies at the National Ignition Facility.

TL;DR: Evidence is presented, through simulations and experiments, that contaminants do not fully reach thermal equilibrium, and thus their amount is usually underestimated.

TL;DR: The following describes the current NIF NIS design and compares the predicted performance with the NIF specifications that must be satisfied to generate images that can be interpreted to understand results of a particular shot and shows NIS model calculations of the expected NIF images based on component evaluations at Omega.
