Superconducting cavities are responsible for beam acceleration in superconducting linear accelerators. Challenging cavity control specifications necessary to reduce radio frequency (RF) costs and maximize the availability of accelerator. Cavity detuning bandwidth two critical parameters monitor when operating particle is strongly related power required generate desired accelerating gradient. RF losses. A sudden increase can indicate presence a quench or multipacting event. Therefore,...
Linear accelerators, like the Free-electron LASer in Hamburg (FLASH) or European X-Ray Free Electron Laser (E-XFEL) take advantage of digital Low Level Radio Frequency (LLRF) system to control phase and amplitude an electromagnetic field inside superconducting cavities. The real-time LLRF system, processing data within a few microseconds, has fulfil performance requirements provide comprehensive monitoring diagnostics. AMC-based controller (DAMC-TCK7) board was developed as general purpose...
Modern digital low level radio frequency (RF) control systems used to stabilize the accelerating field in facilities, such as free electron laser Hamburg or European X-ray laser, are based on programmable gate array (FPGA) technology. Presently, these accelerator facilities operated with pulsed RF. In future, will operate continuous wave (CW), which requires significant modifications real-time feedbacks realized within FPGA. For example, higher loaded quality factor of superconducting RF...
Stable and reproducible generation of a photon beam at Free Electron Lasers (FELs) necessitates low energy spread the electron beam. This is disturbed by various factors. A level radio frequency (LLRF) control system stabilizes RF field inside accelerating modules, as amplitude phase fluctuations are main bunch-to-bunch sources. paper describes architecture LLRF based on Micro-Telecommunications Computing Architecture (MTCA.4) platform developed PCI Industrial Computer Manufacturers Group...

Vacuum-tube amplifiers are the most widespread type of radio frequency (RF) sources used to produce high-power signals needed for beam acceleration in superconducting cavities. At Deutsches Elektronen-Synchrotron (DESY), megawatt-rated klystrons millisecond-long RF shots pulsed operation particle accelerators. In contrast, inductive output tubes (IOTs) provide a continuous signal continuous-wave (CW) operation. both cases, suffer from amplitude-dependent nonlinearity between driving and...
The recent introduction of advanced hardware architectures such as the Micro Telecommunications Computing Architecture (MTCA) caused a change in approach to implementation control schemes many fields. development has been moving away from traditional programming languages ( C/C++), description (VHDL, Verilog), which are used FPGA development. With MATLAB/Simulink it is possible describe complex systems with block diagrams and simulate their behavior. Those then by HDL experts implement...
