Ultra-high Precision in Low Level RF


Problem We Solve: High Energy Physics (HEP) experiments, such as those conducted at particle accelerators and synchrotrons, require extremely precise control and synchronization of beam dynamics to achieve accurate and meaningful results. Any deviation or instability in the radio frequency (RF) systems can lead to significant errors, data loss, or even equipment damage. The challenge lies in maintaining ultra-high precision and stability in RF signals under the demanding environmental conditions of HEP experiments.

Why It Is Important: The success of HEP experiments hinges on the accuracy and stability of the low-level RF (LLRF) systems. These systems are crucial for controlling the acceleration process and maintaining the beam quality throughout the acceleration cycle. Precise control over the LLRF is essential for advancing our understanding of fundamental particles and forces, contributing to groundbreaking discoveries and technological innovations.

How We Solve It: Safran’s Low-Level Radio Frequency (LLRF) system is specifically designed to meet the stringent requirements of HEP applications offering an accurate control of electromagnetic field inside the any accelerating cavities and playing a key role in the overall performance of any particle accelerator. Safran’s solution is tailored on customer needs. With an RF frequency reference based either on White Rabbit technology (Ethernet-based network protocol designed for sub-nanosecond accuracy over fiber optic cables) or external frequency reference, the LLRF system ensures precise synchronization of all the RF signals generated by the system, crucial for maintaining beam stability and quality.

Safran’s solution is compatible with White Rabbit technology as well as RF frequency distribution network (Mater Oscillator). These strategies ensure that all components of the LLRF system, are perfectly synchronized. This is critical for coordinating the timing of different accelerators and beam lines, ensuring that every part of the experiment operates in perfect harmony.
