The Department of the Interior, specifically the U.S. Geological Survey (USGS), intends to award a purchase order for an Energy-Dispersive (EDS) Detector to Oxford Instruments America, Inc. This procurement aims to replace the existing UltimMax40 EDS detector at the USGS Cascades Volcano Observatory in Vancouver, WA, with a new UltimMax100 model that must be compatible with the current scanning electron microscope system. The detector is crucial for advancing scientific research and monitoring volcanic activity, ensuring the observatory can leverage the latest EDS technology while minimizing integration challenges.
