Abstract:
1. A method for stripping electrons from charged particles, comprising the steps of: providing a tandem accelerator comprising: forming a vacuum seal between said carbon stripping foil and said vacuum tube; passing positively charged particles, of the charged particles, through said carbon stripping foil; stripping electrons from the positively charged particles using said carbon stripping foil, said step of stripping electrons forming cations with a charge of at least five; using said carbon stripping foil to block nitrogen gas from passing from a first side of said carbon stripping foil to a second side of said carbon stripping foil; providing a first vacuum pump connected to said vacuum tube on the first side of said carbon stripping foil; providing a second vacuum pump connected to said vacuum tube on the second side of said carbon stripping foil; using said first vacuum pump to maintain a first vacuum pressure that is at least ten times greater than a second pressure maintained using said second vacuum pump; and maintaining a synchrotron vacuum in a synchrotron using said second vacuum pump.
