Preliminary Physics Analysis of GDT-based Neutron Source for Hybrid Application

摘要

The Gas Dynamic Trap (GDT) is a kind of axisymmetric simple mirror stabilized by magnetic expanders, with a very high mirror ratio of a few tens, and with a mirror to mirror length much greater than an effective mean free path of warm ions scattering into the loss cone. Progress of GDT experiment in Novosibirsk encourages extrapolation to a fusion neutron source, mainly because of its high beta value approaching 60% and relatively simple structure. In this contribution, we analyzed some general principles of GDT and its fusion neutron source application, and a GDT-based fusion neutron source is designed for hybrid application.
