Re: General Fusion

<t>looks like the standard 'bigger hammer' approach applied to sonofusion. in this case they also appear to have fed the hammer steroids.<br/> <br/> appart from the interesting engineering solutions they are going to have to come up with, i don't think it will work. it just looks fundamentally too e...

Re: S.T.A.R. Instability hypothesis

376nF!! thats HUGE! at 100 kV thats 1.9kJ! i suspect your meter is wrong. if its not, then no wonder stuff isn't working right

was the PSU connected when you made that measurement?

Re: Contemplation of CANR-LENR investigations

<t>I too was hopping to avoid the calorimetry as doing it well seems to be somewhat non-trivial. the problem is, its such a usefull initial is it?/isn't it? test when one doesn't know weather ones palladium is active or not.<br/> <br/> one possibility might be some sort of self-sustaining device. a ...

Re: beware of unknown o-rings?..

<t>an amusing story:<br/> I once purchased one of these o-ring kits from ebay for vacuum work. it turned out that the things smelt horrible (indicating something volatile in them) and this smell not surprisingly got all over the vacuum system. being determined not to be beaten however, i dumped some...

Re: Chamber Complete

<r>looks like you made the same mistake i made when welding my chamber the first time: too much current. finished TIG welds should look pale orangey or blueish, shiney and smooth like the slightly oxidized stainless. if there matt and grey, then you have too much current. they also tend to be a bit ...

Re: Brush Inner Grids

thats very interesting.

i wonder if a compleatly random homogonious lump of stuff was used, weather the ion beams would melt out paths. would be interesting to see what geomitery it formed.

Re: oops! Ordered wrong half nipples?

<r>rotatable and non-rotatable CF flanges are compleatly compatable. only differance is (as you corectly guessed) rotatable flanges have a ring with the bolt holes in seperate from the pipe and the knife edge. <br/> <br/> it shouldn;t be a problem, you'l just have a rather rattely fusor intil you bo...

Re: UK Radiation License requirement ?

<r>hehe AmBe sources are a bit hefty though. aproxamatly 20GBq Am-241 is required for about 1M N/s IIRC. they also produce considerable high energy gammas.<br/> <br/> while the exemption orders i mensioned are very valid, and in common use, thy do not extend to high activity sources, though some are...

Re: UK Radiation License requirement ?

<r>regarding sources, there is a test equipment exemption from IRR99 this allows small companies (and presumably individuals) to own low activity sealed check sources without a licence for calibration of instruments. In fact i'm currently attempting to purchase some gamma check sources. <br/> some o...
