Update 2015/1

Last winter was used for collecting more parts for the Fusor. The passed 5 months no actual work could be done on the Fusor because we change our residence half-yearly and it is not possible to take the load of equipment with me. Despite the fact that my Fusor setup has an oil diffusion pump in the ...

Re: My first XRT and some questions

Thank you all for the valuable advises. I shall set up a number of tests as recommended. I have a function generator and a scope, so at least this should bring me some results. The core is -as far as I can see- probably all iron as can be seen in the image: http://www.fusor.eu/Images/xraytrafo3a.jpg...

Re: My first XRT and some questions

Thank you, Chris, for your answer. It is indeed the question if this is mains or higher frequency operated. I have the impression that the XRT is rather modern and that makes higher frequency operated more plausible. This is something I need to find out. Thank you, Thomas, for your reply. I'm sorry ...

My first XRT and some questions

Yesterday I received a first, fresh XRT (shown in the image below) still dripping oil from its core. I was told that it is a Siemens 85 kVp at 15 mA dental XRT, running on 230 V AC. http://fusor.eu/Images/Xraytrans02.jpg The XRT has for its rather small size quite some iron in the core (weight 9 kg)...

Re: Update

Thank you, Richard. I was not aware that these special gauges existed. The IR10 was relatively cheap, around 25 EUR, and I succeeded in finding the controller that is required for this gauge: the Ionivac IM 110 or 110D. In the forum posts I found references to the IM 210 controller but that one is f...

Update since introduction

Since my introduction mid-June this year I have been busy to sort out a few things and to collect some gear on a low budget approach. After two months it appeared to me a good opportunity to update the Fusor community about some progress made so far. Most of my spare time went in searching the forum...

Re: Need Help With Alcatel Diffusion Pump

Despite the fact that this post is over seven years old I thought it worthwhile to give the explanation to the text on the terminal box of this diffusion pump, because it might help others who acquire a similar pump of German origin. sw = Ph-Hhzg: this means black (sw = schwarz) = Phase (Ph) - Main ...
