Re: Silver Activation From Hell - 18MeV Clinac.

Haha, Tyler had to email me a photoshopped picture to really see it. The object in the screen of the Clinac 6EX is an arm holding a camera.

I can assure you no rabbits were harmed in the process of yesterday's shenanigans.

Re: Silver Activation From Hell - 18MeV Clinac.

<t>Carl kindly covered everything of significance in this context, the only thing I'd stand to say is that in photon mode these machines are accelerating beam currents between 20-50mA resulting in a dose of approximately 700Rads/minute. I don't know exactly what the continuum of X-Rays looks like on...

Silver Activation From Hell - 18MeV Clinac.

<r>I took the day to play with a few Clinacs in town and thought I'd share what is probably the hottest silver activation on record here.<br/> <br/> The procedure was to sandwich a 1 troy-ounce .99 fine Vienna Philharmonic between two wax bricks and nuke it from orbit with the 18MeV Linac in photon ...

Re: First Neutrons (Unofficial)

<t>Richard, Conrad is still in high-school, I believe this qualifies him to be mentioned in the High School Achievers Section.<br/> <br/> Congratulations Conrad, well done. <br/> <br/> Now try to improve what you've got so far. A good start would be a valve that lets you valve off your fusor to leav...

Re: Is there an optimum voltage?

<t>Rob, <br/> <br/> Finding working, second hand lab grade supplies or X-ray transformers can be tricky, not to mention expensive. Don't get me wrong, they rock, but few here have that kind of $$$ to spend on a power supply.<br/> <br/> I'm a proponent of mains frequency multipliers due to their modu...

Re: Interesting new IPhone geiger counter app/hardware combo

<r>I've heard of this app, it's would seem mostly useless for the intended application, novelty aside. However, using the CCD of a digital camera to detect radiation isn't that uncommon, and can be pretty spectacular not to mention just plain amusing.<br/> <br/> Fusor VS. my iPod: <URL url="http://w...

Re: DOH Health Physicist speaks to Seattle Fusor Group

<t>I must also applaud what Carl has done as he's effectively acted as a popularizer making the DOH among others not just accepting of fusors but encouraging too, not to mention made projects (a few orders of magnitude more interesting than the typical sad classroom demos) available to kids who will...

Re: Fusion short answer?

Was there a point to this thread?

I wouldn't call it the the best Haiku for the ITER I've heard but it's a start I suppose.

Re: Ultra high vac and hydrogen concentration.

<t>Fusors don't ever cross into the realm of UHV, perhaps HV during the initial evacuation but most fusors operate in the realm of 3-12 microns depending on the setup, guns etc. <br/> <br/> The benefit of having UHV and HV capable pumps far outweighs the couple extra bucks spent. With my diffusion p...
