Hello All,
I am about to start building a 10 stage 450kv marx bank. this thing will be 225nf per stage capacitance using pulse caps. Obviously this is seriously high power and am looking to throw some ideas about regarding protection of electrical equipment in vicinity!!! I am assuming nasty induced voltages and some serious noise.
should this beast be inside a faraday cage? my suspicion is yes.

hi Colin I built these marxes
and I got to about 800kv with 3.5ft arcs and with these caps it went off like a gunshot and to fast to see. it is a fun and dangerous project. it started getting to heavy to move so it will have to be built in sections I hope to finish it some day. You should make some shorting sticks so you can short one cap at a time case you lose some charging resistors. EMP is a pausiblity so a open or shielded place is a good idea. so all expensive equipment should be unpluged and put away. what do the caps look like

Yes I think shielding is going to be needed so may build a faraday cage. Yes the discharge probe is going to be important. Safety around this is going to be essential.
Nice lookingmarx there and love the multiplier design :)

OK I am already talking myself out of this project! All the effort and cost then what will be left? A unit so powerful I cant fire it at home or if i do maybe wipe out electronics, blow things to pieces. Then after firing a few times what do I do with it? A tesla coil discharge is fully visible and exciting whereas the marx is likely going to flash so quick and so loud i wont see much.
Maybe a seriously powerful accelerator of some kind woul dbe more interesting?
