There is a website at http://accelconf.web.cern.ch/accelconf/p99/KW/KW/KW133.HTM
with lots of interesting 3 page papers on accelerator technology. I found the following paper "The Plasma Window: A Windowless High Pressure-Vacuum Interface for Various Accelerator Applications" there:

It describes using a 4cm stabilized arc in a 3mm dia tube to keep a vacuum between electron tubes, lasers or accelerators and atmospheric pressure (and up to 40 psi) targets.

With a "travelling wave accelerator", a microwave powered vacuum pump might be created that would only require a roughing pump. Ions shoot towards the pump, electrons into the fusor to provide ionization.

A travelling wave or helical microwave accelerator could be as simple as a glass tube in a pipe with washers or helical wire wrapped around it. Simple in construction, complicated in design and alignment. Any thoughts?
