In recent years, several scientific groups have investigated X-ray generation by peeling adhesive tape in vacuum. X-ray generation results from electron emission during the peeling and their interactions with surrounding materials. These studies mainly focused on the tape, system properties, and electron interactions near the detachment point. We examine electron interactions with solid materials along their travel path. We observe a non-homogeneous spatial distribution of electron energies, which we compare with numerical simulations. It shows peeling adhesive tape can serve as a simple, low-cost X-ray source for educational demonstrations and small lab experiments.
