| Popis: |
A new type of biperiodic accelerating structure is described. The coaxial coupled structure makes use of coaxial cavities isolated from direct beam excitation to couple power between adjacent accelerating cells. The advantages of the π 2 - mode are therefore available for application in storage rings at a loss in shunt impedance of 7%. Parasitic modes in on-axis coupled biperiodic systems are reduced by half and excitation of beam blowup (BBU) modes by a simulated off-axis beam show that the sensitivity of the coaxial coupling cells to BBU modes is two orders of magnitude smaller than for on-axis coupling cells. |
