I have been able to create a demo fusor. My power supply is a half wave rectified neon sign transformer that is putting out a peak of -7.5 kv. My grid is made of tungsten wire and I have recently acquired a Diffusion pump and electric pneumatic gate from an old SEM.
I plan to get an X-ray transformer soon and upgrade my wiring insulation and a new cart in the near future.
Sorry for the bad camera work.
