One of the LLRF system's core functions is controlling the RF field for particle beam
acceleration. An RF controller implements feedback or feedforward algorithms, regulating …

This book begins with an overview of the RF control concepts and strategies. It then
introduces RF system models for optimizing the system parameters to satisfy beam …

In the past two decades accelerator controls and feedback systems have changed
dramatically. While in the past relatively simple analog systems were used, present systems …

The LCLC RF gun requires a water based thermal system to tune the resonance frequency
of the cavity to 2856.03 MHz. The RF system operates in pulsed mode with bursts of 2-3 …

It is well know in the" control community" that a good feedback controller design is deeply
rooted in the physics of the system. For example, when accelerating the beam we must keep …

As more accelerators adopt superconducting cavities or require high RF field stability, the
LLRF system becomes critical for meeting the accelerator performance objectives. Different …

Low-level radio frequency (LLRF) systems of particle accelerators become more critical
because they become a limiting factor with the increasing RF field stability requirements …

Abstract A Soft X-ray Free Electron Laser Test Facility (SXFELTF) based on normal
conducting linear accelerator was constructed at the Shanghai Synchrotron Radiation …

Low-level RF (LLRF) control hardware and its embedded programming plays a pivotal role
in the performance of an accelerator. Modern designs implement most of the signal …

The Los Alamos Neutron Science Center (LANSCE) proton accelerator is scheduled for
refurbishment. A new low level radio frequency (LLRF) system is part of the refurbishment …
