From theCambridge English Corpus The instability conditions (34) and (35) simply state that the growth due to the fusion products exceeds the damping coming from the backgrounddeuteriumplasma. From theCambridge English Corpus Thermonuclear burn performance of volumeignited and centrally ignited baredeuterium-tritium microspheres. From theCambridge English Corpus Numerical study of fast ignition of ablatively implodeddeuterium-tritium fusion capsules by ultra-intense proton beams. From theCambridge English Corpus By electrolysis, the heavy water separated into oxygen, which collected at the platinum electrode, anddeuterium, which accumulated at the palladium electrode. From theCambridge English Corpus We use the solution for calculating the effect of particle trapping on neutron production for beam-heateddeuteriumplasmas. From theCambridge English Corpus Also, in this plasma edge region, the temperatures of the carbon impurity ions and thedeuteriumions are equal to each other. From theCambridge English Corpus The existence of high energy ions is further confirmed by the occurrence of fusion reactions indeuteriumclusters.

From theCambridge English Corpus The field particles that are responsible for ' dressing ' the bare test particle are the ions and electrons of the backgrounddeuteriumplasma. From theCambridge English Corpus The heat flux fromdeuteriumto the target and to the shell is assumed to be zero. From theCambridge English Corpus The same ion temperature was assumed as a reasonable estimate for the case ofdeuteriumplasma.
