Multipurpose RF field Vector Controller for linear accelerators

The paper describes the design and the implementation of the flexible, multipurpose RF (Radio Frequency) field Vector Controller for the linear accelerators based on the superconducting technology. The implementation is done for the FPGA (Field Programmable Gate Array) based LLRF (Low Level Radio Frequency) control systems. The full process of the requirement analysis and the library implementation is presented. It is followed by the description of the controller´s applications and the results of the performance tests. The controller fulfills the requirements of the various accelerator facilities and hardware platforms and can be easily adapted for the planned experiments to decrease their cost by avoiding expensive research and development phase.
