Subject: Re: [TSSP] A naive question about discharge elongation
Hi Marco, I agree, everything that I've looked at refers to DC fields, 50/60Hz AC, single pulses, etc. Nothing I've seen (outside of the TC community) reports measurements on repetitive bursts of HV RF. We know from experience that HV RF punches out much longer discharges that could reasonably be expected from the less fierce waveforms normally studied. It seems reasonable to assume that there are optimum parameters for RF frequency, burst length, and repetition rate, just waiting to be found and accounted for. > Is the TC long discharge mechanism analysed, modeled and > known in the literature or isn't? I don't think it is. Single, isolated half cycles are often discussed, but these seem to be quite of long duration, eg 100's of uS. I've seen some fairly sophisticated models of the leader formation process taking place during an isolated half cycle, but nothing which takes account of previous half cycles, existing leader channels and space charge, etc. But others on this list are better acquainted with the literature. -- Paul Nicholson --
