Thanks for all the input so far. I am gravitating towards a switching HV supplier (like the 555 style) plus a multisegment CW multiplier. Could somebody advise on the capacitors in the multiplier? I understand that the capacitance influences the drop and the ripple voltage (as does the switching frequency). It's nicely and simply explained eg. here http://home.earthlink.net/~jimlux/hv/cw1.htm But how would it look from a practical point of view for this particular application? What kind of capacitors would work the best? What switching frequency would be practically best suited? Thanks, Marcin
