This was so helpful! Thank you, but I think this post would also be good in the Basics section of the forum.

There is a shop in Florida that makes some of the ion source parts for this cyclotron. http://www.mtialbany.com/wp-content/uploads/2014/05/rds111-cc.pdf

PCG are more forgiving when it comes to mounting process and appear, by beam on foil time, to last longer, at least for the lower energy. Arc evap version is more easy to break than PCG. Also from experience, with humidity, the foils react different to absorption of water. The arc evap maybe hold more moisture, the cyclotron must pump down and dry out the foil, or it will explode with the water upon beam strike. The PCG is better about staying dry.

Please show how to put foil on frame? Thank you.
