摘要

In order to study the neutron measurement techniques set up in laser interaction experiments with D–T filled targets, we have designed and operated a 14‐MeV neutron short pulse source. The device is a sealed neutron gas tube with a hot cathode supplied by an adjustable high‐voltage pulse generator. Its principle consists in discharging a coaxial cable, held at the generator voltage, into the high‐impedance neutron head. We then obtain a neutron pulse train with each pulse duration determined by the length of the cable. This source generates a total routine yield of 107 neutrons. A small sized head will be inserted into interaction chambers.
