One of the things we have been considering is selling a "turnkey" version of the WB-7. In this case we would design, build, license and deliver an operating Polywell, probably on the scale of the present machine. Operator training and tech support would also be part of the deal. The model is to use...

Numerical modeling...

I read recently that Tri-Alpha was recently financed to the tune of $40 million. This suggests that they will be doing some hardware experimentation in the near future. My understanding is that the financiers are not just Paul Allen, but include Venrock Associates (they funded Apple in the late 70's...

Norman Rostaker?

Does anyone know anything about Norman Rostaker's group? I believe this is called Tri-Alpha and that they are set-up in the Foothills area of SoCal. Any new info about them?

Thanks...

I just read the previous threads about FPGeneration and about POPS, in general. POPS is essentially a pulsed bias such that you have an oscillating plasma sheath. POPS is interesting to me because it reminds me of a specialized coating process technology called Plasma Source Ion Immersion (PSII). Th...

Questions about FPGeneration

I stumbled upon a website (www.fpgeneration.com), which describes a mutli-pole ion source version of an IEC polywell. The guy, Alex Klein, has previously worked with Dr. Bussard. Can anyone here comment on Alex Klein's MIX approach to polywell fusion and how it compares with Dr. Bussard's approach? ...

DeviceNet and CAN

Yes, DeviceNet uses CAN as the physical layer. DeviceNet is the communication protocol that runs on CAN and is starting to become popularly used in semiconductor and other high-vacuum process tools. The advantages is that much of the control and instrumentation such as power supplies, MFCs, and vacu...

DeviceNet

DeviceNet is a deterministic protocol that can be implemented through an ethernet cable. Much of the vacuum system instrumentation (MFSs, temperature controllers, ion source power supplies) come with devicenet interfaces. You can also get DeviceNet interface modules for most of the major PLC brands ...

Turbo pumps and base pressure

I saw your comments about turbo pumps on your "power and control" blog. An effective way to increase the pumping capacity of a turbo pump to reach a lower base pressure is to add a cryotrap between the main valve and the turbo pump. This will make it easier to get to a lower base pressure, say 10-9 ...

100 page technical paper

Joe, It will be great to add the direct interview link to your page of Polywell references. MSimon, thanks for the link Does anybody know about the 100 pages technical paper about Polywell promised by Dr. on the Google video? Has it been released to any technical issue? I agree with Keegan that Ant...
