Description
The X-band lineariser linac planned to be installed on CLARA will be aligned using beam induced higher order modes (HOMs). Higher order modes in the cavity were studied using a bead-pull measurement technique. A software application was developed in LabVIEW to control the 3D motorised bead position scanning setup and VNA for S-parameter measurements. Propagation of HOM frequencies in the linac were verified, identifying the most suitable HOMs to use. Progress in development of HOM signal processing hardware system with dynamic control is also discussed in the paper.
