Description
Existing magnetrons, primarily employed for investigating control methods and lifespan enhancements in superconducting radiofrequency (SRF) accelerators, were originally designed for diverse applications such as kitchen microwave ovens (1kW, 2.45 GHz) or industrial heating (100 kW, 915 MHz). Our paper describes our collaboration with Richardson Electronics LLC (RELL), focusing on the development of rapid and adaptable manufacturing techniques.
These techniques include enabling innovative phase and amplitude injection locking control methods, extending the magnetron's lifespan and enabling cost-effective refurbishing, ultimately aiming for the lowest possible life-cycle costs.
Our objective is to test modified magnetron sources to power SRF cavities to accelerate an electron beam. We plan to construct and evaluate a magnetron operating with our patented subcritical voltage operation methods specifically tailored for driving an SRF cavity.
Our focus in this endeavor is identifying and addressing critical areas in magnetron manufacturing and design that significantly influence life-cycle costs. These areas encompass optimizing Qext (external quality factor), improving filament design, fine-tuning the magnetic field, enhancing vane design, and introducing innovative strategies for controlling outgassing.
Our ultimate goal is to transform these devices, originally intended for disparate applications, into highly efficient components for driving SRF cavities. Through these advancements, we aim to achieve superior performance, prolonged durability, and significantly reduced life-cycle costs for magnetrons utilized in SRF accelerators.
