What is a drift tube?
One of the earliest practical linac structures, the Drift Tube Linac structure, accomplishes the complex chore of acceleration with the aid of “drift tubes” distributed along the axis of the structure. The particles are exposed to the longitudinal electric fields when they are in the accelerating direction and are hidden from the electric fields by the drift tubes when the electric fields are in the opposite direction. As the velocities of the particles increase, the lengths of the drift tubes must also increase to keep pace with the particles. Incorporated into the design of all RF linacs is the ability to bunch and focus the particles into small packets suitable for efficient acceleration.
