We studied D + D fusion reactions at the CELIA/ECLIPSE laser facility. These reactions were triggered by focusing the ECLIPSE laser (up to 100 mJ on target, pulse duration of 40fs and focal spot of 10μm FWHM) on a solid C2D4 target. By detecting the 2.5MeV neutrons, produced in the D + D fusion reaction, using C6D6 scintillators in a time-of-flight experimental set-up, we measured a rate of a few hundred fusions per shot. At the same time, we detected also energetic ions (up to a few 100 keV) using time-of-flight diamond detectors. The experimental set-up will be presented and the results discussed and compared with dedicated simulations.

Abstract
We studied D + D fusion reactions at the CELIA/ECLIPSE laser facility. These reactions were triggered by focusing the ECLIPSE laser (up to 100 mJ on target, pulse duration of 40fs and focal spot of 10μm FWHM) on a solid C2D4 target. By detecting the 2.5MeV neutrons, produced in the D + D fusion reaction, using C6D6 scintillators in a time-of-flight experimental set-up, we measured a rate of a few hundred fusions per shot. At the same time, we detected also energetic ions (up to a few 100 keV) using time-of-flight diamond detectors. The experimental set-up will be presented and the results discussed and compared with dedicated simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
