Enhanced fast digital integrator for magnetic measurements.

Area of Science:

• High-energy physics instrumentation
• Electrical engineering
• Metrology

Background:

• The Fast Digital Integrator (FDI) is crucial for magnetic measurements in particle accelerators at CERN.
• Existing FDI performance limitations necessitate an upgraded solution.
• On-field exploitation has revealed specific areas for improvement in accuracy and data handling.

Purpose of the Study:

• To prototype an enhanced Fast Digital Integrator (eFDI) meeting new operational requirements.
• To improve key performance metrics such as offset, self-calibration accuracy, and data throughput.
• To validate the eFDI's performance against the current state-of-the-art FDI.

Main Methods:

• Design and prototyping of the enhanced Fast Digital Integrator (eFDI).
• Implementation of advanced self-calibration techniques.
• Metrological characterization of the eFDI prototype.
• Comparative analysis of eFDI and existing FDI performance.

Main Results:

• Achieved offset of 5 ppm on a 10 V full-scale range.
• Self-calibration accuracy with a residual error of 1 ppm.
• Data throughput increased to 100 MB/s.
• Maintained high signal-to-noise and distortion ratio (SINAD) of 105 dB at 10 Hz.

Conclusions:

• The eFDI prototype demonstrates significant performance enhancements over the previous FDI.
• The new design successfully addresses the requirements for advanced magnetic measurements at CERN.
• The eFDI represents a substantial improvement in precision and efficiency for particle accelerator instrumentation.
