uTCA / Stand-alone LLRF

Our digital RF stabilization system is available on the uTCA or stand-alone form-factors for best in-class LLRF solutions.

Overview

Our digital RF stabilization system is available on the uTCA or stand-alone form-factors for best in-class LLRF solutions. They are our new fully digital RF systems designed to offer an accurate control of electromagnetic field inside the any accelerating cavities and playing a key role in the overall performance of any particle accelerator. Our solution is tailored on customer needs and take full advantage of our previous expertise on PCIe-S LLRF equipment now working with the most advance crate technologies.

uTCA LLRF

Stand-alone LLRF

Interfaces

- Up to 2 LLRF channels on the same box
- Up to 2 configurable RF output
- Up to 7 configurable RF inputs
- One Frequency reference input
- 7 configurable input/outputs TTL connectors
- It can be mounted on two different configurations according to user needs:
  - Fits into a stand-alone 19 inch rack
  - Fits into a 19 inch rack using 2U height and integrated into a uTCA backplane

Features

Continuous and pulsed amplitude and phase or amplitude and frequency cavity field control
Opened loop or closed loop mode control of amplitude and frequency or phase.
Pulse shaping feature for smoothing RF pulses
Feedforward for beam loading compensation
Real-time monitoring of RF signals (Incident, reflected, cavity field …)
Provides information for step tuner motors
VSWR (arcing/reflection) detection and handling events: when it receives a reflection signal above a user-defined threshold, it shuts off RF output for a time period also defined by the user.
Fast output interlock system (Machine protection)
EPICS control system support and easy user interface
Postmortem analysis with selectable event triggers and configurable capture parameters. MATLAB, python, CSS/BOY libraries for post processing.
Compatible with White-Rabbit and IEEE-1588 protocols. Seamless integration into the Timing system for triggering and timestamping control operations.

Main performance highlights

• Amplitude stability: 0.02%
• Phase stability: 0.3 degree
• Amplitude precision: 0.03% Vpp
• Phase precision: 0.03 degree
• PI delay (input to output delay): below 1us
• RMS jitter: 182 fs (LLRF output jitter working in closed-loop with amplitude and phase control)
