Neutron emission as high as ${10}^{7}$ is observed when a high intensity (a few ${10}^{19}\mathrm{W}/{\mathrm{cm}}^{2}$) subpicosecond laser pulse at 529 nm wavelength is focused on a deuterated polyethylene target. Neutron emission is also measured

First 14 MeV neutron images of imploded microballoons have been obtained at the Phebus laser facility at CEL‐V in 1992 [Garconnet et al. Laser Part Beams 11, 3 (1994)]. The sizes of the neutron source have been measured by using a coded‐aperture

The first 14-MeV neutron images of imploded microballoons have been obtained on the Phébus laser facility at CEL-V. The sizes of the source have been measured, in direct-drive experiments, by means of a coded-aperture imaging system. The principle i

New diagnostics were implemented on the implosion experiments performed at LULI to improve our measurements of hydroefficiencies: Neutron chronometry gives the time of emission of the fusion reaction products as measured from the peak of the laser pu

We are developing neutron diagnostics to characterize the implosions performed with the Phebus laser, operating at 5 kJ blue light delivered in 1·3 ns. For measuring the glass pusher areal density, (ρΔR), of the target, a silicon radiochemistry di

To study deuterium‐tritium mixture implosion conditions on laser fusion experiments, we developed very high‐speed photoconductive devices. The targets are irradiated by the 1.3‐ns, 5‐kJ blue light of the two beams of the Phebus laser. The neu

Penumbral images of neutron distributions form laser fusion experiments provided by large aperture imaging systems are degraded by signal-dependent noise. Most image processing algorithms assume that the signal and the noise are stationary. The purpo

Neutron source images of a compressed DT target burn region were obtained in 1994 on the Phebus laser facility at CEL-V, by using a penumbral imaging technique. The symmetric biconical aperture generates a signal-dependent noise which degrades the sp
