3 – Examples of linac accelerating g structures: a. protons, p , b. electrons, c. heavy y ions 16
Disc-loaded structures operating in 0-<strong>mode</strong> The Drift Tube Linac (Alvarez) Add tubes for high shunt impedance 2 advantages of the 0-<strong>mode</strong>: 1. the fields are such that if we eliminate the walls between cells the fields are not affected, but we have less RF currents and higher shunt impedance. 2. The “drift tubes” can be long (~0.75 βλ), the particles are inside the tubes when the electric fi field ld is i decelerating, d l ti and d we have h space to t introduce focusing elements (quadrupoles) inside the tubes. Maximize coupling between cells → remove completely the walls 17
