Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Experiments on plasma heating in open magnetic traps require a powerful electron beam with pulse length of 0.1–1 ms. Such a beam is expected to obtain in the source with a plasma cathode and high perveance multiaperture electron optical system. An appropriate technology is being developed at Budker Institute of Nuclear Physics (BINP), Novosibirsk. Here we introduce a prototype electron beam injector with the following design parameters: energy of electrons up to 150 keV, pulse duration of >0.1 ms and beam current up to a few hundred amperes. The injector is intended to operate in an external axial magnetic field of ~0.1 T. In this paper, the design of injector prototype is described and the first test experiments are presented.
