The anode would have helium gas pumped through, in order to keep its surface below 800K or so. The outside of the vacuum chamber and other parts (eg. the capacitors) can be conventionally water cooled.
What temperatures would you anticipate stemming from the fusion produced electron particle beam meeting the solenoid? Will the beam be collimated like a laser beam or more diffused as we see with jets in space. Does the solenoid need special materials and cooling treatment as well?
When I asked that question (more or less) Eric communicated that the plasmoid, in the final incarnation, will intercept and absorb most of the electron beam directly, so that it doesn’t significantly erode the base of the anode. So I take it that there will be no exiting electron beam at all.
