Re: vacuum acquired!!

<t>richard, roberto<br/> thanks much for the advice. i did check the pump oil, and it is clean but discolored- somewhat of a yellowish color. i guess its old? anyway i will change it before i power it up. i haven't pulled the diff pump apart yet, but plan to do that in the next few days. and yes, th...

Re: vacuum acquired!!

<t>hi richard,<br/> yeah, that sounds like the same unit. it's even got some sort of solonoid valve between the two stages, i guess as an isolation valve? perhaps if the mechanical pump fails it shuts the valve...<br/> anyway i'm not very expiranced with vacuum equipment (this is why i STILL haven't...

vacuum acquired!!

<t>while at richard's this last weekend for the heas event, i was able to pick up a nice li'l vacuum station. it's a Vacuum Barrier Corp. model 9005; it's got a Welch 1400 mechanical pump and what looks like a 3" oil diffusion pump, all in one convienent unit. i'm quite pleased with this aquisition ...

Re: Direct radiation-to-electricity conversion

if you want to use the neutrons, a hybrid design might be more usable. use the fusor as a neutron source to drive a subcritical pile... (search the forum for "hybrid" there has been much discussion on this in the past)

Re: Russians achieve P-B11 reaction using Lasers

<t>well, if you've the knowlege and the cash, ebay usually is a good place to find parts. you have to be patient though. also look around for medical lasers. i have an old medi-lase 2 (~100 watt Nd-YAG) that was being replaced with a much smaller and less electricity hungry diode pumped unit. (i obt...

Re: Russians achieve P-B11 reaction using Lasers

<t>i dont see a way of attempting a P-B11 reaction at the amature level unless one were to use some sort of targeted system. for example, use a boron electrode in place of the central grid in a fusor. of course, the voltage needed will be much higher, which will make the standard fusor scheme unreal...

Re: Lightbulbs??

zuo,
very interesting. how large is this "bulb" fusor?

i'm not sure what the purpose of such a design would be. perhaps a portable neutron source?

Re: Laser Ionization

for that matter, doesn't a deuterium discharge produce lots of uv anyway? (deuterium lamps, for example)
