Nuclear diagnostics in support of inertial confinement fusion experiments (invited)
- Lawrence Livermore National Laboratory, Livermore, California 94550 (United States)
As the yields of inertial confinement fusion (ICF) experiments increase to National Ignition Facility levels new diagnostic techniques for studying details of fusion burn behavior will become feasible. The new techniques will provide improved measurements of fusion burn temperature and history. Improved temperature measurements might be achieved with magnetic spectroscopy of fusion neutrons. High-bandwidth fusion reaction history will be measured with fusion-specific {gamma}-ray diagnostics. Additional energy-resolved {gamma}-ray diagnostics might be able to study a selection of specific behaviors during fusion burn. Present ICF yields greater that 10{sup 13} neutrons are sufficient to demonstrate the basic methods that underlie the new techniques. As ICF yields increase, the diagnostics designs can be adjusted accordingly in order to provide clear and specific data on fusion burn performance. {copyright} {ital 1997 American Institute of Physics.}
