Measurements of Areal Densities and Temperatures from DT Capsule Implosions on OMEGA
Abstract
Spectral measurements were made of 14.1-MeV neutron knock-on particles from imploded DT-filled CH shells on OMEGA. Fuel ρR is inferred from the spectra and yields of D and T knock-ons, while shell ρR is determined from the measured yield of p knock-ons from the CH. Shell electron temperature Te is uniquely determined by using the downshift of the endpoint energies of knock-ons from the fuel. This is possible because knock-on yield is independent of Te while the energy downshift is a function of both shell ρR and shell T_e. In addition, CD and CH shells were also shot. From such implosions, a complex set of multiple particle spectra are obtained simultaneously. This work was performed in part at the LLE NLUF, and was supported in part by the U.S. DOE Contr. DE-FG03-99SF21782, LLE subcont. PO410025G, LLNL subcont. B313975, and by the U.S. DOE Office of ICF under Coop. Agree. No. DE-FC03-92SF19460.
