摘要：

Relativistic electron beams driven by laser wakefield acceleration were utilized to produce ultrashort neutron sources. The experiment was carried out on the 38 fs, ～0.5 J, 800 nm Ti:Sapphire laser in the 10 TW UT3laser lab at University of Texas at Austin. The target gas was a high density pulsed gas jet composed of 90% He and 10% N2. The laser pulse with a peak intensity of 1.5 × 1018W/cm2interacted with the target to create a cylindrical plasma channel of 60 μm radius（FWHM） and 1.5 mm length（FWHM）. Electron beams of ～80 p C with the Gaussian energy distribution centered at 37 Me V and a width of 30 Me V（FWHM） were produced via laser wakefield acceleration. Neutron fluences of～2.4 × 10～6per shot with hundreds of ps temporal length were generated through bremsstrahlung and subsequent photoneutron reactions in a26.6 mm thick tungsten converter. Results were compared with those of simulations using EPOCH and GEANT4, showing agreement in electron spectrum, neutron fluence, neutron angular distribution and conversion rate.
