Today we started to stick the first parts together.
The doublecross is DN100.

Wow! This is gonna' be a big boy! Wish I had a piece of chalk. ( there is a back story) As I am also a model railroader there is a real story about the Union Pacific Railroad ordering the largest locomotive ever made in a fleet of these steam locos in the early 40's. As the first one of these million pound + locos rolled out of the builder shops, some unknown worker took a big piece of white chalk and wrote in big foot tall letters on the front smoke box cover... "Big Boy"... The name stuck and that group or class of engines acquired that worker's moniker for all time.

This fusor is truly going to be a big boy among fusors, once it is lit up!

Wow, that is a beautiful, big, clean system you are building there! Love the large windows. Can't wait to see it in action! Just checked out your introduction, nice to see someone so close to me (I live near Budapest), building such a wonderful fusor. Maybe one day I'll hop over and take a look :). Eventually we'll have fusion cons around here! (unless I missed it and there already are happening, which is perfectly possible considering how I've been out of the loop!)

Ps.: That HV feedthrough with the massive insulator made me drool!

Very nice but I would need two insulators. $$$$$ :-(

Re: Archived - European Fusor - HV-PS

Hi friends of the high voltage!

My new HV-transformator just arrived!

Here some data:
30 kV
2 kVA !!!
about 60 kg of material ;-)
including a thermal circuit breaker adjusted to 75°C.

This will create about 42 kV DC at approx. 50 mA - I love it!
If it's not enough, I can add another one reaching 84 kV - but this seems to be toooo much!
Four of them would reach the voltage for p-B11 :-)))
No, I'm kidding!

I will test it this Friday - whish me luck.

Good luck with that transformer, Werner. :-)

Did you have it made to order, or was it designed for something else?
What are all those primary taps for?
Will it be used under oil?

OK, I had bad luck!

Unfortunatly, after just reaching 18 kV, we had an arc between the HV coil and the core.
End of the story - I will try to let it repair on monday.
Isolation has to be improved or I have to submerge it in oil - what I tried to avoid.

Here you see two pics showing the corona discharge close to the rectifier diodes (in the darker picture) and the whole setup (built together with Philipp).

@ Rich: The primary taps are to pre-adjust voltage.

OK, here is the solution to my last problem:
The Isolation at the bottom of the HV coils was optimized with this black isolation resin.

Should work now!
I'll keep you informed.

Hi friends of fusion!

Within the next weeks I will travel to ITER.org together with some Austrian scientists. We will have a Special tour and also meet some of the guys working at the superconducting components. Pictures will be available in October.

Her ist an actual picture of my new CF double cross ready to be connected to the turbo. The old Iso-KF thing has to go ...


BR,
Werner
