Ignition Delay Times of Kerosene (Jet-A)/Air Mixtures

open access: yes, 2014
Ignition of Jet-A/air mixtures was studied behind reflected shock waves. Heating of shock tube at temperature of 150 C was used to prepare a homogeneous fuel mixture. Ignition delay times were measured from OH emission at 309 nm and from absorption of He-

Three-dimensional fast electron transport for ignition-scale inertial fusion capsules [PDF]

open access: yes, 2006
Three-dimensional hybrid PIC simulations are presented to study electron energy transport and deposition in a full-scale fast ignition configuration. Multi-prong core heating close to ignition is found when a few GA, few PW beam is injected.

An Atomic‐Level Bimetallic MOF Platform Overcoming the Stability‐Performance Tradeoff for Laser Propulsion

open access: yesAdvanced Materials, EarlyView.
This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...

Laser ignitability of insensitive propellants [PDF]

open access: yesAdvanced Material Science, 2018
Laser ignition tests were conducted on insensitive propellants formulated with an insensitive filler (1,1‑diamino-2,2-dinitroethylene, commercially known as FOX-7) and with either energetic or non-energetic binders: poly3-nitromethyl-3-methyloxetane (PolyNIMMO) and hydroxyl-terminated polybutadiene (HTPB), respectively.

Pulsed DC Sputter Deposition of Stable Turbostratic Boron Nitride Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Boron nitride (BN) films are deposited by sputtering from a boron target. During deposition, a substrate bias voltage is applied between the plasma and the sample, which reduces excess boron in the film and enhances the crystallinity. This process prevents the formation of boric acid and ammonium borate hydrate.

Analysis of hohlraum energetics of the SG series and the NIF experiments with energy balance model

open access: yesMatter and Radiation at Extremes, 2017
The basic energy balance model is applied to analyze the hohlraum energetics data from the Shenguang (SG) series laser facilities and the National Ignition Facility (NIF) experiments published in the past few years.

On the change in Inertial Confinement Fusion Implosions upon using an ab initio multiphase DT equation of state

open access: yes, 2011
Improving the description of the equation of state (EoS) of deuterium-tritium (DT) has recently been shown to change significantly the gain of an Inertial Confinement Fusion (ICF) target (Hu et al., PRL 104, 235003 (2010)).
