Re: First Plasma Achieved

Installed a new grid and slightly upgraded the vacuum line today. Played around with the plasma color at different pressures too.

Open Course on Plasma Physics Currently Available

I thought some people here may find this interesting. There is a free open course on Plasma Physics currently being offered by the Swiss Federal Institute of Technology on the site edx.org. It seems anyone who is familiar with calculus and introductory E&M should be able to handle it. https://www.ed...

Time a properly sealed chamber should hold a high vacuum?

My chamber tends to lose its vacuum pretty fast when I turn off the pump. About how long should a properly sealed fusor chamber hold a high vacuum when you turn off the pump?

Re: First Plasma Achieved

Fixed some of the leaks today. Got the pressure down to about 65 micron. Ended up with a whitish plasma this time.

First Plasma Achieved

It is not optimal as the pressure is it not nearly as low as it should be and the grid is not very nice looking, but it is my first time generating plasma.

Re: New Power Supply

Probably, but if you spend some time searching you could find a used supply for a lot less. Or you can do what a lot of people on here do and build one.

Demo fusor almost complete

I just need one more small piece for the demo fusor stage (backordered vacuum tubing), and then around 3-5 more significant pieces to see if I can do fusion.

Re: What type of connector is on this vacuum pump?

It is the normal hose barb found on virtually all precision direct drive pumps. This is for a direct hose connection with clamp. I suggest a suitable length of hose from the pump to a KF series to hose barb adaptor, commonly available. From there the KF to CF adapter. Going straight from the mechan...

What type of connector is on this vacuum pump?

Is anyone able to identify this connector on my DD-100 pump? Also would you know what type of adapter I need to connect it to CF chamber?
