Lead Shield for HPGE Detectors


The Kolga Model A360 is a 10 cm (4 inch) high performance copper/tin-lined lead shield for germanium detectors (HPGE). The A360 shield is made from certified DOE Run virgin low back-ground lead. The graded liner is designed to suppress lead x-rays and consists of a 1 mm (0.040in.) tin layer covered by a 1.5 mm (0.06 in.) oxygen-free copper layer. The front opening/ split top is a full 10 cm (4 inch) lead shield to provide the best possible shielding and most convenience for sample loading. The shield includes a rigid stand with adjustable feet to maintain the unit level while allowing easy access to install or remove the detector. The A360 exterior and stand are coated with durable epoxy paint. All copper components are coated with a clear polyurethane sealer to prevent corrosion.
