Ruhmkorff coil

I want to build a Ruhmkorff or spark coil for more power for my X-ray tube and a Tesla coil. It is a high voltage transformer and I need at last some 50 kV. If you have any information of how to build such device, then write it here please.

Find the book: "Induction Coils: How to Make, Use, and Repair Them"

I saw a couple available on good books. Here is one link:,+Use,+and+Repair+Them&hl=en&ei=eEwBTJeOFIv-NYKfmTw&sa=X&oi=book_result&ct=result&resnum=2&ved=0CDMQ6AEwAQ#v=onepage&q&f=false

but there are others. Good luck!
