Abstract
This thesis deals with the design of a higher order mode beam position monitor (HOMBPM) using dipole modes in third harmonic 3.9 GHz accelerating cavities. HOMBPM has the capability of measuring beam positions inside the accelerating module without additional vacuum components. Conventional BPMs fall short of providing this information directly. The amplitude of the dipole mode has a linear dependence on the transverse position of the excitation bunch. This enables the diagnostics by measuring these dipole modes extracted from HOM couplers.
