Re: Star Mode (American University)

<t>Doug,<br/> <br/> Thanks for the idea of putting a crap piece of glass in there. I'll definitely do that. I'm not going to test if the e-beam is an ebeam with a magnet because It would require me to put my hand near it during operation.....that's not going to happen when i'm getting 350,000 CPM in...

Archived - Star Mode (American University)

<t>Recently our 30 year old HV supply died, so we had to get a new one. We picked up a Bertan 30KV 10ma constant power supply. I was worried it wouldn't perform, I was wrong. <br/> <br/> After a week of twelve hour days in order to prepare for the university's research conference, I'm excited to giv...

Re: First Plasma (American University)

Steve, the grid does in fact have 3 circles, not two! The angles just poor!

Archived - First Plasma (American University)

<t>After starting on this project in novemeber, ordering the parts a month ago, we have assembled the chamber, pumped down to 2.8 mTorr, and created a star mode.<br/> <br/> I will show you pictures of the chamber, lowest possible pressure, and pictures of the star mode.<br/> <br/> The first picture ...

Re: Fusor CAD models

Really nice Ben. Unfortunately I don't have the expertise to make something such as that or the time to learn how to.

Re: Final Design

<t>Just read through everyone's comments.<br/> <br/> First thing, thanks for all the comments and praise, means a lot to me.<br/> <br/> Secondly, some asked, but I have Autodesk Autocad 10 64-Bit. The way I designed (most) of this chamber is by going to Kurt Lesker's website. On the left hand side t...

Final Design

<t>Welp, here it is. After quite a bit of time my whole team has our design worked out, complete with 6" view port! Parts will be ordered in the coming week and assembled. Some holes/tapping will be needed but it shouldn't be too tedious. Tell me what you think.<br/> <br/> If you're curious I can se...

Re: Advantages of the Dual Hemisphere?

<t>Doug to the rescue.<br/> <br/> Always great advice. Really thought provoking. Although I'm super attracted to the aesthetically pleasing and interesting design of the spherical chamber I think you convinced me to use this cross that I found lying around in the department. The knife edges are fine...

Re: Advantages of the Dual Hemisphere?

The reason I've brought this up is that I've found a 4 way cross just lying around. The OD of the flanges is 6", so I would need some reducers.

Adrian, How small is your chamber?

Re: Advantages of the Dual Hemisphere?

The main question is Why is the dual hemisphere design predominate?
