The Central Nervous System for High-Energy Physics: The GFT3001
As presented in this publication from ICALEPCS, Greenfield Systems provides a sophisticated commercial solution for the rigorous timing requirements of large-scale physics experiments. The GFT3001 Master Oscillator Transmitter serves as the central “brain” of a picosecond timing system, designed to synchronize complex equipment across facilities spanning up to 100,000 square feet.
Unmatched Precision and Scalability
In experiments involving Petawatt lasers or Synchrotrons, synchronization is critical. The GFT3001 coordinates a serial data stream over an optical network to local multi-channel digital delay generators. This architecture allows for:
- Massive Scale: Coordination of up to 256 local areas and the generation of 2,500 delayed triggers.
- High Resolution: Exceptional 1 ps timing resolution with a system jitter typically below 15 ps
- Dynamic Laser Chains: Precise control over pump-lasers, Q-switches, and Pockels cells within a laser chain, ensuring optimal plasma heating and ignition in target chambers.
Reliability in Real-World Applications
The GFT3001 is not just a theoretical solution; it is the proven standard at prestigious facilities such as the Laser MegaJoule (LMJ), Synchrotron Soleil, and LULI. Real-world measurements included in the paper demonstrate the system’s ability to maintain peak performance in temperature-stabilized environments, providing the stability necessary for long-term operational success.
Flexible Integration and Control
Modern physics requires adaptable tools. The GFT3001 supports both internal and external clock references and offers user-programmable sequences, including repetitive single shots, single bursts, and repetitive bursts. With an embedded web interface and compatibility with Labview, Tango, and EPICS, the GFT3001 integrates seamlessly into any advanced laboratory control network via Ethernet.
By implementing the GFT3001, researchers gain the scalable, high-fidelity timing backbone required to master the challenges of high-energy physics.
