Abstract

Graphene foils improve angular and energy resolution in neutral atom detectors while also improving mass discrimination and usable energy ranges. We developed improved grid supports and achieved areas >10 cm² with good foil coverage and significant improvements in secondary electron yield from ~1 nm metal oxide overcoats. We present Luxel’s characterization of large-area graphene foils for applications as transmission filters and detector components.
