Abstract
A method of producing an ion beam in a tandem accelerator, the method includes the acts of insulating, in a cavity containing an insulating gas under pressure, a beam tube having first and second ends and a terminal situated between the first and second ends; seating, using a load lock valve, the insulating gas under pressure; generating an operating voltage using a first voltage source situated outside the cavity when the operating voltage is less than or equal to a threshold value; generating the operating voltage using a second voltage source situated inside the cavity when the operating voltage is greater than the threshold value; coupling the terminal to the first or second voltage sources; generating, using a particle source, an ion beam; and accelerating the ion beam in a first and second parts of the beam tube.
