NIM BIN- current draw of NIM modules vs. supply

<t>Hello-<br/> <br/> the PS (220V type) of my NIM BIN has the following specification:<br/> +12V 1A<br/> -12V 0.5 A<br/> +24V 0.5A<br/> -24V 0.5A<br/> +6V 3A<br/> 117V 0.1A<br/> The modules I am using have a consumption of approx 0.25A from the 117V output- the other voltages should be fine.<br/> I ...

Re: why does my driver get hot

<t>Hi-<br/> <br/> listening to all your tips and learning a lot I finally am pumping out some power.<br/> I used a different IGBT board (from an old xray- supply) because I understood that brute force is not the way to go for now.<br/> I built a driver with a TL494 giving me the waveform I need for ...

Re: Need pro comments before building ICP

<t>Hi-<br/> <br/> as Chris already pointed out- more details on the construction would be fine. <br/> My first thought also was: will not work with coil outside a steel chamber.. <br/> Or is the coil in the chamber? Otherwise you will need a (quartz) glass tube to contain the plasma.<br/> <br/> Gree...

Re: A 'multi-purpose' chamber with multiple HV HF feedthroughs.

<t>Hi-<br/> <br/> nice setup!<br/> Just one thing you should think off (even though your Glass is rock solid)- <br/> if the Glass shatters (I also expect this can easily happen due to thermal stress from ebeam,...) you probably will have a nice new doorstop:<br/> your turbo- pump....!<br/> <br/> Gre...

Re: Archived - University of Utah's new demo fusor

<t>Hi <br/> <br/> really nice pictures of a nice clean setup! <br/> I guess if you have a sensitive Neutron Detector and a supply just a little bigger (perhaps use a Variac and a 110V to 220V transformer to power the NST? do not fry it...) you will have the proof it works soon.<br/> Also pretty cool...

Re: Main chamber completed

Whow-

a bling-bling chamber! Good work- looks really beautyful! I hope the inner surface is as smooth and clean?

Set up of Gamma Discrimination: 10 uCi BA133 sufficient? (BF3 or He3 tube)

<t>Hello-<br/> <br/> I can borrow a 10 uCi BA133 source. <br/> I am wondering if this source is strong enough to clearly have lots of gamma pulses from my Neutron Tubes to set up the HV and discriminator level fast and easily?<br/> It is recommended to use a "super hot ore sample or a big radium dia...

Re: A forum for non fusion related radiation detection:

Hi Geo-

thank you for these links- they indeed are very interesting!
What forum would you suggest for questions like the one I had about the static master?

Kind regards

I also changed my post later on: i think even though probably beginner question- ok here ;-)

<t>Hi-<br/> <br/> I think Richard pointed in this "delete or Not delete that is the question here" discussion <br/> out: everything radiation and Safety related might be discussed in this Forum as it is important for the hobby fusioneer <br/> I really would appreciate all answers on this- see it thi...
