The main task of the interlock system is to prevent any damage from the cost expensive components of the RF station. The implementation of the interlock should guarantee a maximum uninterrupted time of operation which implies the implementation of self diagnostic and repair strategies on module basis. Additional tasks include collection and temporary storage of status information of individual channels;...
The Spallation Neutron Source low level RF team includes members from Lawrence Berkeley, Los Alamos, and Oak Ridge national laboratories. The team is responsible for the development, fabrication and commissioning of 98 low level RF (LLRF) control systems for maintaining RF amplitude and phase control in the front end (FE), linac and high energy beam transport (HEBT) sections of the SNS accelerator,...
The low-level RF (LLRF) control system for the Spallation Neutron Source has undergone some recent hardware changes. The intended field and resonance control module (FRCM) design has been re-vamped to minimize functionality and ease implementation. This effort spans a variety of disciplines, and requires parallel development with distinct interface controls. This paper will discuss the platform chosen,...
