I have been looking at ways of producing 20 - 30 KV power supplies inexpensively.
One possible solution is the DC-HVDC converters available from http://www.emcohighvoltage.com
This vendor does offer a 0-30KV regulated powersupply for ~$450 US which isn't unreasonable.

Individual DC-HVDC converters can also be purchased. The highest end unit is a E121 which can
produce about 15KV (~$135 US). A E101 is also available that can produce up to 10KV ($128 US).
These E101's have recently been posted for sale on ebay by a user who has a surplus supply, so
limited numbers are available for ~half price. I am currently in the process of purchasing 2 of these.
I may be able to get a functioning Ce system going for education purposes with the 10KV source.
If however, I can couple these 2 units together I will have a sufficient power supply for many
CE experiments.

Does anyone have any experience in this area ?

I will keep you posted on my progress.

R.O'B
