Exactly what voltage and current levels do I need? 

I would like to build a negative ion generator. From what I
understand, a negative ion generator has a very high voltage
(thousands) and a very low current. This voltage is fed into a
very-high-voltage diode (oriented to pass the negative voltage but
reject the positive voltage). The resulting very high negative voltage
is fed into a very sharp object (such as a sewing needle), which
injects the negative ions into the air inside the chassis. A nearby
fan disperses the negative ions into the air in the room outside the
chassis.

Exactly what voltage and current levels do I need? (I also realize
that I must simulate this in PSPICE, because the tiny current levels
and huge voltage levels aren't in a range that regular multimeters can
handle.) I have heard that using too much power will produce ozone,
which is poisonous.
