The aim of the role is to provide a high degree of senior technical support to the RF group focussing in particular on low level RF and electronics, to provide a leading role in the development of a new digital low level RF (LLRF) system and to develop and maintain the present analogue LLRF system, and to support the operation of the RF plant; including management of all aspects of assigned technical projects.



Key responsibilities include:


·         Senior level contribution to the overall work of the RF Group;

·         Responsible for LLRF, RF distribution, drive amplifiers, phase/gain units, master oscillator(MO) and associated equipment, including:

-      Management of all aspects of the LLRF;

-      Characterisation, maintenance, and operation of LLRF;

-      Day-to-day checks and performance analysis;

-      Spares holding and availability;

-      Safety and statutory inspections;

-      Ensuring that drawings are accurate and up-to-date;

-      Ensure state of the art performance and reliability is maintained;

-      Manage future development of LLRF;

-      Carry out calculations, design and comparison of theory and measurement of the existing system and any full or part upgrades;

-      Ongoing review of performance against current and new requirements;

·         Responsible for the safe and effective management of the RF Lab;

·         Contribute to the characterisation and documentation of the high power amplifier systems and cavities;

·         Responsible for providing operating instructions and training for the Operating Team for LLRF, drive amplifiers, phase/gain units, MO and associated equipment RF distribution;
