Coilgun switching
hi hi im planing on building a strong coilgun (give or take 5kv per each coil) and need a switching mechanism which cna handle taht load and do so quickly.My original idea was pneumatic switches however i think those would be way too slow. Next i thought gas switches could work. The idea being is I have a spark gap which is enclosed in a metal box where a vacuum is pulledd. Then when i need to quench the arching i would pump in either sf6 or nitgrogen gas. Howeveri have been told by dubious sources that this wouldnt work. Does anyone have any opinions or ideas for fast and accurate switching systems? Please keep in mind cost and availability. Thank yo ufro your time and i wish you a wonderful day
