Patent ID: 10037863

Abstract:
The invention comprises a method and apparatus for slowing positively charged particles, comprising the steps of: (1) transporting the positively charged particles from an accelerator, along a beam transport line, and into a nozzle system; (2) placing a first liquid in a first chamber in a beam path of the positively charged particles; (3) placing a second liquid in a second chamber in the beam path of the positively charged particles; (4) moving the first and second chamber with the nozzle system; (5) slowing the positively charged particles using the first liquid and the second liquid; (6) moving the first chamber in a first direction to yield a longer first pathlength of the positively charged particles through the first chamber; and (7) moving the second chamber opposite the first direction to yield a longer second pathlength of the positively charged particles through the second chamber.
