Enhancing Data Acquisition Speed and Processing Efficiency in Electron Spectroscopy Power Supplies

Electron spectroscopy systems require highly stable and precisely variable high-voltage power sources to scan energy levels accurately. Traditional designs often sacrifice acquisition speed for precision. To overcome this, a dual-loop control architecture with high-speed DACs and parallel data processing is introduced.
The outer loop maintains long-term voltage accuracy, while the inner loop enables rapid response and fine current control. Segment-based voltage scanning allows fast acquisition without compromising energy resolution. By implementing parallel sampling and interpolation, the system can increase measurement speed by over 30%.
Signal quality is preserved using adaptive noise filtering based on wavelet transform techniques, which separate true spectral peaks from environmental noise in real time. FPGA-based parallel computation allows for simultaneous data collection, processing, and visualization.
Temperature drift compensation and auto-zero calibration routines ensure consistent energy scale alignment, even during continuous multi-hour operation. The result is a faster, more reliable power supply system that supports high-throughput, high-precision spectroscopy.
