Physics-guided data expansion for photocathodes using TESS transverse momentum measurements
Year: 2026
Type: conference-paper
Abstract: Precise characterisation of photocathode mean transverse energy is critical for optimising electron beam quality. This paper presents a physics-informed image processing pipeline using Transverse Energy Spread Spectrometer data (231–291 nm), incorporating Gaussian PSF fitting, Wiener deconvolution, resolution equalisation, and noise-aware augmentation. A high-fidelity dataset of 6500 synthetic images was generated, achieving average SSIM = 0.997 and $ R^2 \approx 0.98 $, enabling robust MTE prediction and supporting future ML-based diagnostics for next-generation photoinjectors.
