| 1 | Ion acceleration and neutron production in hybrid gas-puff z-pinches on the GIT-12 and HAWK generators显示文摘Z-pinch experiments with a hybrid configuration of a deuterium gas puff have been carried out on theHAWK(NRL,Washington,DC)and GIT-12(IHCE,Tomsk)pulsed power generators at 0.7 MA and 3MA currents,respectively.On GIT-12,neutron yields reached an average value of 231012 neutrons,and deuterons were accelerated up to an energy of 30 MeV.This was 50 times the ion energy provided by the generator driving voltage of 0.6 MV and the highest energy observed in z-pinches and dense plasma foci.To confirm these unique results independently on another device,we performed several experimental campaigns on theHAWKgenerator.Comparison of the experiments onGIT-12 andHAWKhelped us to understand which parameters are essential for optimized neutron production.Since theHAWKgenerator is of a similar pulsed power architecture as GIT-12,the experiments on GIT-12 and HAWK are important for the study of how charged-particle acceleration scales with the current. | D.Klir S.L.Jackson A.V.Shishlov V.A.Kokshenev K.Rezac A.R.Beresnyak R.K.Cherdizov J.Cikhardt B.Cikhardtova G.N.Dudkin J.T.Engelbrecht F.I.Fursov J.Krasa J.Kravarik P.Kubes N.E.Kurmaev V.Munzar N.A.Ratakhin K.Turek V.A.Varlachev | 2020 | Matter and Radiation at Extremes2020，5，2： | 0 |
| 2 | Generation of high-energy neutrons with the 300-ps-laser system PALS显示文摘The laser system PALS,as a driver of a broad-beam ion source,delivered deuterons which generated neutrons with energies higher than 14 Me V through the 7Li(d,n)8 Be reaction.Deuterons with sub-Me V energy were accelerated from the front surface of a massive CD2 target in the backward direction with respect to the laser beam vector.Simultaneously,neutrons were emitted from the primary CD2 target and a secondary Li F catcher.The total maximum measured neutron yield from 2D(d,n)3He,7Li(d,n)8Be,12C(d,n)13N reactions was ~3.5(±0.5) × 108 neutrons/shot. | J.Krsa D.Klír A.Velyhan E.Krousky M.Pfeifer K.Rez J.Cikhardt K.Turek J.Ullschmied K.Jungwirth | 2014 | High Power Laser Science and Engineering2014，2，3： | 0 |
