Development and Evaluation of a CNN-Based Charged-Particle Event Rejection Algorithm for Soft X-ray Detection in a pnCCD-Based Satellite System
A CNN trained on 5x5 pixel charge patterns rejects beta-ray background in a pnCCD at 3.1% misclassification versus 10-12% for grade methods, with 98.1% X-ray acceptance in the tested >1.4 keV range.
