"Using high frequency HV will be more effective than HV DC in ion
generation. "


Ok, ionization using high frequency HV is more effective, but if I
need for instance, a pure production of negative ions, I think that
high frequency HV is not good to perform that because It will
generate equally positive ions and negative ions (following HV
alternations, in positive cycles atoms become positive, and in
negative cycles they become negative)... ¿or what I don´t know about?
¿what am I wrong?(ionization process seems to be not so easy to
understand as It looks)
