Delivery of an electro-optic waveguide prototype for demonstration at RHUL test bench

Task 10.7 aims to develop novel electric field sensors for use in high-bandwidth accelerator beam diagnostics. The technology chosen to achieve the fast response time required is based on fibre-coupled optical waveguides made from lithium niobate. Prototype waveguides were developed in collaboration with a UK industrial partner and delivered to Royal Holloway University of London (RHUL), where they were integrated into an optimized design of electromagnetic pick-up, suitable for subsequent beam tests at CERN. The integrated electro-optical pick-up was bench at RHUL tested using a 20 GHz vector network analyzer and a fast photodetector data acquisition system. The delivery of the hardware and demonstrated operation of the prototype in the laboratory fulfills the ‘delivery of an electro-optic waveguide prototype for demonstration at RHUL test bench’
