Abstract

Active alignment algorithms for linear colliders such as the Compact LInear Collider (CLIC), require measurements of beam positions inside accelerating structures in order to control short and long-range transverse wakefields. Highly-damped accelerating structures offer the possibility that damping waveguides can provide position signals so the accelerating structure itself can be used to make these position measurements. A demonstration of beam position measurement using a 3 GHz slotted iris structure with a dipole mode Q≈16 was made in CTF II (CLIC Test Facility) and results are compared to computations using HFSS and GdfidL.
