The effect should be more noticable in systems with smooth electrodes operated at "the edge of breakout"-in a narrow range between Malcolm's experiment and state of no discharge at all. Theoreticaly,there could be certain DC voltage superimposed to regular TC voltage becouse of space charge "rectification vice" formed region by previous shoots if: a)Suitable BPS rate is applied to allow described kind of overall charge field equilibrium b)Difusion cofficients,rate of electrostatic repulsion and relaxation times between ions low enough and in line with all said. ..as concerns breakout absence from Terry's OLTC rod-sphere geometry something is definitely wrong.Catch in current msms/registration (maybe displacement vs. conductive current issue problems) or something is wrong in modelling max E field. Even in single shot mode of 38 kHz there can not be 100 kv/cm at your electrode system without some discharge going on there! Terry,have you tried to observe per see in a complete dark like Malcolm did?Also,you may try reversing a polarity. Regards, Boris __________________________________________________ Do you Yahoo!?
