Compact Radiation Shield with Honeycomb Structure and Metal-Mesh Filter for Molecular Detectors

DESCRIPTION

This paper presents a compact radiation shielding solution featuring a fine honeycomb structure paired with a self-standing metal-mesh infrared filter. Designed for superconducting array molecule detectors, the setup effectively manages heat load exceeding 100 mW and provides long-range shielding for large-scale array detectors. Performance metrics reveal significant energy resolution improvements with detailed specifications of the detector sizes and temperature controls. This innovation enhances the efficacy of molecular detection through optimized design and materials.
