Variable-energy drift-tube linacs
Practical applications of ion linacs are more viable now than ever before because of the recent development of the radio-frequency quadrupole accelerating structure, as well as other technological advances developed under the Pion Generator for Medical Irradiations program. A practical technique for varying the energy of drift-tube linacs and thus further broadening the possibilities for linac applications is described. This technique involves using the post couplers (normally used to flatten and stabilize the electric field) to create a step in the fields, thus terminating the acceleration process. Using this technique and a 70-MeV accelerator design, the examples show that energy is variable continuously down to 20 MeV, and a small energy spread is maintained.
