Gadolinium foil (light tight) is vital in neutron capture applications due to its high thermal neutron absorption cross-section, making it a key material for radiation shielding in nuclear reactors and particle detectors. Its paramagnetic properties are leveraged in low-temperature physics and electron transport experiments, particularly in advanced research on magnetic materials. Our expertise enables us to produce pinhole-free foils across a variety of thicknesses. Additionally, its light-tight characteristics support high-precision optical experiments and radiation protection applications in the laboratory, ensuring minimal external interference in scientific instrumentation and radiation detection systems.
