Description
Today particle accelerators have a broad range of applications in fundamental science, medicine and industry. In the past the achievement of performance goals such as beam energy, beam power or other qualifying beam parameters were the primary objectives for accelerator development. With the advanced technologies available today it is often well known how such goals can be achieved, and now the efficient and cost effective utilization of electrical power gets increasingly into focus. For accelerators with high beam power the conversion efficiency from grid to beam is of utmost importance, e.g. ESS, ILC, CLIC, LHeC. Conventional state of the art RF sources cannot reach the efficiency targets set by these future colliders.

There is currently significant research effort into the studying the efficiency of conventional power sources and the exploration of new devices and concepts, e.g. multi-beam IOT’s with solid state driver; magnetrons with better stability. Within the network EnEfficient the aim of this two day workshop is to address several topics related to the energy efficiency of high power RF sources and to stimulate advances and innovations in this field. The workshop will cover advances and experience primarily in Klystrons, IOTs, Magnetrons, Tetrodes and high power SSA systems.

Interested speakers should contact Dr C Lingwood (c.lingwood@lancs.ac.uk).
Student Bursaries are available.
