Thanks for all responses about the power stick of Gemini 300 magnet. Sorry
not provinding enough information of the magnet. Here is what I know:
the magnet is made by Varian about 10 years ago. It is a Varian built
magnet with an 60 days helium hold time and a 7 day nitrogen hold time (I
think - this one is several years old and I don't have the specifications
any more.) It is known as the R2D2 in the community. The drift rate was
probably 10 Hz/hr when it was new. I beleive that it is a narrow bore 51 mm
system. I would like to buy an new/used stick. If anyone has a spare part
and willing to sell it, let know soon. Thanks for your attention!
