ABSTRACT

ABSTRACT

Consumer imaging sensors (CIS) are examined for real-time charged-particle detection and CR-39 plastic detector replacement. Removing cover glass from CIS is hard if not impossible, in particular for the latest inexpensive webcam models. We show that $10-class CIS are sensitive to MeV and higher energy protons and α-particles by using a 90Sr ß-source with its cover glass in place. Indirect, real-time, high-resolution detection is also feasible when combining CIS with a ZnSAg phosphor screen and optics. Noise reduction in CIS is nevertheless important for the indirect approach.
