The Laboratory for the Study of Accelerating and Radiofrequency Structures (LESAR) is in charge of developing the radiofrequency systems required for particle accelerator operation.   Albeit the laboratory main activity focuses on accelerating cavities, research is also carried out for other critical components, such as power couplers, cavity mechanical and piezoelectric tuners, and accelerating voltage stabilization systems. These components are designed using simulation codes, some of them are developed in-house. The qualification process makes extensive use of prototyping and testing under realistic operating conditions.   Improving the performance of accelerating cavities ... More »
