Written by GovTribe AI · Dec 21, 2023

This document outlines specifications for a direct electron detector and analysis system for electron backscatter diffraction (EBSD) being procured by the Naval Research Laboratory. The system must include a direct electron detector capable of measuring patterns from 3-30kV with single electron sensitivity, 512x512 pixels, and integration times from 15-50ms. It must be able to capture and index at least 85 patterns per second with 0.1 degree orientation precision. The system also requires three computers, EBSD and pattern simulation software, installation, training, documentation, and a one year extended warranty. Bidders must deliver the system to the Naval Research Laboratory in Washington, D.C. and provide on-site validation and user training. This procurement is being conducted under solicitation N00173-23-RFI-CY24.
