In fact, I think he may have been the first to used grids for the purpose of electrostatic confinement, unlike Farnsworth and Hirsch who used ion guns exclusively as it seems.


This is not correct. In late 1965 and early 66 Hirsch made up a grided simple fusor without any ion guns at all! This machine was actually demonstrated producing neutrons (10e7/sec) powered by a simple wall outlet in the conference room at the AEC! (Much to the stunned amazement of the megawatt Princeton onlookers and AEC officials.)

I have a period photo of Gene Meeks and Steve Blasing standing beside the system, assembled on a roll-around stainless steel hotel maid's cleanup cart!!!! Real slick, and just impressed the hell out of the wheels at the AEC. So much so that within a year, they had hired Hirsch into an AEC management position!! With Farnsworth retired, and Hirsch hired away, this effectively ended the ITT/Farnsworth effort.

It is true that all of Farnsworth's machines used ion guns, but Meeks and Hirsch studied the simple grided systems for about 1 1/2 years at the end. They have a patent on same. RH

I can give
>you some references to Lavrent'yev's papers for your study and consideration if you so desire.

Yes, please give us the refs. I haven't heard of Lavrent'yev's effort and am most interested.
