Do you know what Q, the "Air consumption rate" might be referring to? I don't see where any air is being "consumed".
I can find the pressure of the air at the open end of the cylinder, and I know the pressure at the bottom of the cylinder. Assuming I know those and several other things I...
Hello,
As we know, when you blow over the neck of a bottle, it resonates at a certain frequency.
I want to build a cylinder that will resonate at a certain wind speed: 4 mph or about 1.78 m/s
I definitely know how to find the resonant frequency of a cylinder. However, I'm not sure what...
I have an engineering problem that I have to solve.
Imagine that we have two electron beams, one originates from a heading of 0, coming toward point A. A line between the origin of beam 1 and point A would create a line of heading 0. Now a second beam, beam 2, originates from a heading of...
The only supplier of them that I found was Kimball Physics, however those seem to be more complicated and advanced guns, which are most likely out of my ~500$ price range. I haven't received a quote from them as of now.
Does anyone know of a good source for small electron guns? Just a simple one. I was using a TV CRT gun but the filaments don't last when exposed to atmosphere. I obviously operate under vacuum but I have no way to store my device in a vacuum for a long period.
I have radiation shields attenuating the x-rays to 0.2%. and I've achieved 0.8 Pascals with the PVC already, any suggestions about better piping/tubing would be appreciated though!
The PVC already sustains a 0.8Pa environment(in a different design), I just need to make connectors for this setup. And there already Helmholtz Coils in there, that are controlled by variable power supplies, at every 45* bend. Each coil's geometry can curve up to 60*.
In June 2011(after the ISEF) I will have EVERYTHING made available to the public, schematics, parts lists, video tutorials, diagrams, and a 20 page paper on how to build it and how it works.
Here's a video of my homemade electron accelerator, named the Aurora Accelerator. To the best of my knowledge it is the largest homemade accelerator ever built. Check it out, and comment!
