An electric discharge as a trap for diffusion pump vacuum systems /

An electrical discharge is used as a trap for a diffusion pump using DC-704 silicone pump fluid. The discharge cracks the pump fluid vapor thus taking it out of the system. In the process much hydrogen and some other lighter gases are evolved.
