Their high performance, small size, and low cost make them the ideal detector for OEM hand-held ap- plications to bench-top analyzers. The silicon drift detector (SDD) enables extremely high count rate applications with excellent energy res- olution. The detector is housed inside the same TO-8 package as AmptekҒs other detectors, so its form-factor is a direct replacement for current systems and is com- patible with all Amptek accessories and options. The Amptek Silicon Drift Detectors (SDD) represent a breakthrough in x-ray detector technology by providing o-the-shelfӔ performance previously available only from expensive cryogenically cooled systems.
