There will be moving parts in the system; coolant pumps, vacuum pumps etc. (multiples of each for redundancy). I was just thinking whether modulating the pressure in the chamber over the course of the cycle would reduce the wear and load on the inner surface and components inside exposed to the few thousand degree plasma that will exist between cycles. Do the benefits outweigh the disadvantages of mechanical parts and extra complexity?

There is a comprimise between cooling the waste heat out of the plasma in the bulk of the chamber between pulses, and letting it cool too far so the it starts recombining and leaving deposits.
