X-ray detector for NDE of metallic AM builds for automated inspection

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding an "X-ray detector for NDE of metallic AM builds for automated inspection" opportunity.

• Panel Size Preference: While not strictly required to be larger than 6" in diameter, a 6" diameter detector is preferred (e.g., 5x6" is better than 1x6").
• Replacement Detector: This is not a replacement for an existing detector.
• Software: Acquisition software for digital radiography is required. It can be assumed if it is free and approved for Federal Government use; otherwise, it must be included in the offer.
• Integration with X-ray Source: The software and detector do not need to be integrated with an existing x-ray source, but the detector should be triggerable remotely.
• Usage: The detector will be mounted on the outside of a vacuum chamber, with x-rays transmitted via a window, not for field inspection.
• Software Installation: NASA prefers to install the software on a local workstation, implying a workstation may need to be provided.

These clarifications may impact the technical specifications and software/hardware requirements for potential bidders. Bidders should ensure their proposals address these points, particularly regarding software acquisition and the preferred detector size and installation method.

Questions & Answers / Clarifications
