that depends on the size of the wire. if 50 ns is the needed rise time (= 1/2 wave, ie: 10MHz), and you can tolerate a .006 ohm resistance, the skin effect limits the wire dimensions (in copper, ρ = R·Area / length = 1.68×10^−8 Ω·m; skin depth= 20.5 μm @10MHz) to a length no more than 7.2 x the circumference.

So, per the formula, a 1″ wire connector could be only a bit less than 2′ long. Tight quarters! The caps would be in a tight ring around the vacuum chamber, I think.
I’d build the ring to minimize distance to the anode, where it exits the base plate, which is at the high voltage system’s ground potential. The extreme is to build with a single cap.
