Advantages of the Dual Hemisphere?

<t>Here's a question I've been wondering about:<br/> What are the advantages of using the dual hemisphere conflat design? Its the predominate chamber that everyone uses. From what I can see, it allows you to use a one grid system because you can use the outer grid as the chamber itself, but its pric...

Re: Reversing High Voltage Polarity

<t>I feel like an idiot. You guys were completely correct....as was I in a sense. I knew it was just going to involve switching wires, but I didn't see this coming! Just rotate the acrylic.<br/> <br/> I did tests today up to around 70% and it looks like the system isn't exactly as linear as I though...

Connecting a Pump to High Vac System

<t>I've been checking out the Vacuum FAQs and I cant find anything about how people are connecting mechanical pumps such as a two stage rotary pump to a steel vacuum chamber. My chamber is going to be pretty standard in design, CF hemispheres with a bunch of 2.75 inch half nipples. What kind of port...

Reversing High Voltage Polarity

<t>Hey All,<br/> <br/> I'm having problem's with my power supply's negative polarity, let me give you some background about the source.<br/> <br/> I have recently started testing the 30KV DC power supply that I have via a high voltage divider circuit. Its fairly old (1979), but has been sitting dorm...

Re: NRL Plasma Formulary

I just wanted to thank you for this resource, everything I needed to Mathematically analyze (that I couldn't get from my undergraduate degree).
