Building now...…..
200mm dia x 200mm long acrylic cylinder with acrylic end plates.
Power supply slung under base acrylic, from 15kV NST I stripped from my old SGTC.
10 ali plates spaced 20mm apart on nylon spacers and bolts with HV on alternate plates.
Argon filled with telltale neoprene disc to show pressure increase as sparking will heat up gas. HV to be cut manually to start with.
Maybe auto later.
Model railway valves for Argon inlet/air outlet.
Non pulsed HV to start with, as the first spark chambers had this so
this is old fashion stuff.
PS. I haven't forgotten 'Bach with sparks,' but as I said somewhere for the moment it's on
'the bach burner.'
