NIM crate voltage tolerances

<t>i have finaly aquired a propper NIM bin, compleat with runners that don't rattle, the corectly threaded holes to screw the nims in, the silly unobtainable puwer plugs and... a dead PSU.<br/> <br/> after getting fed up with trying to repair the crumbling PSU, i have decided it would just be easyer...

Re: Technique for Deuterium Drying

<t>i built a D2 dryer from a coil of copper tubeing and a peltier heat pump, the theory being that the large internal serface area of about 4" of 1/4" tubeing would allow a heigher temperature to be used. unfortunatly the electrolytic watter splitter i spent a lot of time and effort on was a complea...

Re: Hormesis, Again

this is true, i didn't make that very clear in the last post. one must also take into account the biolobigal halflife of the radionuclide in question and the form it was ingested in.

Re: Hormesis, Again

<r>very interesting. i have been moderatly supprised to learn, on my cause, that one can recieve a properly hefty dose of radiation ~3Gy mabey or as much as 20Gy if spread out over a few months and suffer a relativly moderate encrease in ones liklyhood to get cancer, mabey 5% or so, compaired to a 2...

Re: Ion source working, 49 bubs / 3 min!

<r>i second Johns call for a magnetron or general RF FAQ. i have been considering investagating RF ion generation and high power ion resonance in the fusor, but need more information on keeping all that RF where its suppost to be, instead of in my eyes, turbo pump, computer systems and instrumentati...

Re: a very good book on radiation detectors and measurment

oh, i did search the refs section for 'knoll' and didn't find a spesific post about it, i didn;t realise it was general knowledge it does indeed omit the older stuff.

a very good book on radiation detectors and measurment

<t>Radiation Detection and Measurement by Glenn Knoll, 3rd Edition.<br/> <br/> it covers a great many types of detector, explaining how they work, and a great many types of radiation and there intersctions with each other. <br/> i think it also goes into the maths of measurement quite a bit as well....

yes, i mean a neutron scintilator. your probably right about the shippping, i thught it might be a problem

Re: X-ray, Gamma BTI bubble detector

would it be possable to use those bubble detectors to calibrate a scintilation counter, compairing the readings of both from a running fusor? if so, and if one could be sent to the UK, i might be interested if i have enough spair cash at the time.

Re: Hitek 3000 power supply

thats a very nice looking supply Andrew, a great find :)
i wish UK ebay was more forthcomeing with PSUs like this, it is proveing to be the biggest obstical in my persuit of fusion :(
