DC coil without the voltage doubler resoance charge inductor?

Hello all,
DC Coil: I have acquired all the parts and am in various construction phases
of the 11" linear variable rotor 0-500bps spark gap, safety resister banks
(tiger strip network) 3 min bleed down from a 4Uf 20KV Maxwell filter/
smoothing cap. 100k 150 watt safety Bang fiberglass stick. I will short and
ground this before I go down stream!

After pounding my head I see no advantage to a HV charge inductor as I am
able to deliver 20365v @ 8k watts easily with my pig 14400 5kva (harder to
come by in UK I guess) (in a 10KVA tank)Ultimately, I would like to charge ~
80nf with up to X^limit? bps and in the 8kva ball park.

The charge inductor seems to be a source of failure for many who have gone
down this road? I am thinking of retaining my welder and ballasting the LV
side of the pig.

**A few design questions?*** The FW Bridge will be made from  4 stacks
of(6)studded 7.5KV each 4.5a diodes part # hvca hdb7.5 9928 (Altronics).
These should all have a snubber across them yes? Suggested value, type ?

I have a (100) 1N5408 1000v 3or 4 amp doides I was thinking of paralleling 2
and series 40 pairs of these as d-Q is a one nano snubber across each pair
prudent?

Lastly the RF coming back from the tank to reek havoc and pillage the
rectifiers. Searching the achieves, "a simple 1"x 6" open air coil of house
wire should act as block" or HV wire wound on a Large torrid such as a TV
deflection coil?" Are we buying this? I would appreciate some guidance
folks.

Thanks Much
