Well , you didn't tell , why you can't use square wave for your triac ?
is the input of triac sine wave ?
And i can't realize that what is your problem here ??!!

Well i'd connect the Ioniser to the mains with a TRIAC in series. The ioniser is a Cockroft Walton Voltage Multiplier structure (i am puting 30 diodes 1N4007 and 30 * 10nF capacitors). How can i calculate the total current? The simulations gives me this "sinewave" for the Current.
I don't think you need high current , because C/D multipliers can't give currents more than several ma ! don't forget to select appropriate capacitors ( they should tolerate enough ! )
you can select each usual triac simply . and i think because your current is pretty low , you won't need triac ! just opto triac is enough !
Good luck

The main application of an ioniser is to clean the air. What i want to do is to eliminate electrostatic forces of small particles. I don't know if it will work.
Zero crossing is always recommended when the load is not resistive may be you use MOC3041. because the current is low it must not be problem. Also check what is the minimum load current required by the triac for it to properly conduct.
