Glenn,
I like your idea of using .090 poly. Then you should be able to use this
capacitor by itself instead of in series. I would guess it should be good
for 12kv to 13kv operation. By increasing the dielectric from .060 to .090
will decrease the capacitance by about 31% - this should drop the standard
.019 mfd value down to about .013. This is using the full length sheet of
8.0 feet. Since you want .007 which is about 46% less than .013, I would
think your plates should be about 44" long.
Someone check my math here.
