National Ignition Facility (NIF) Neutron time-of-flight (nTOF) Measurements

First Results from Cryogenic Target Implosions on OMEGA

LLE Review, Volume 90 49 Introduction The base-line direct-drive ignition target design for the National Ignition Facility (NIF)1 is a thick cryogenic DT-ice layer enclosed in a thin CH shell.2,3 In direct-drive inertial confinement fusion (ICF)4 a spherical target is illuminated by a large number of laser beams to provide a spherically symmetric implosion. Target implosions with cryogenic DT f...

Signal and background considerations for the MRSt on the National Ignition Facility (NIF).

A Magnetic Recoil Spectrometer (MRSt) has been conceptually designed for time-resolved measurements of the neutron spectrum at the National Ignition Facility. Using the MRSt, the goals are to measure the time-evolution of the spectrum with a time resolution of ∼20-ps and absolute accuracy better than 5%. To meet these goals, a detailed understanding and optimization of the signal and background...

Energy Gain of Magnetized Cylindrical D-T Targets in Fast Ignition Fusion

In recent years, many different plans have been considered to use the nuclear energy gained from inertial confinement fusion (ICF) as attempts to obtain high energy efficiencies. In conventional ICF methods, a small amount (about mg) of the deuterium–tritium compound is confined in a small spherical chamber of a few millimeters in radius and compressed by laser or heavy ion beams with powers in...
