Nondestructive Evaluation Program

Cryogenic Computed Tomography (Cryo CT)

Active Technology Project

Project Introduction

X-ray Computed Tomography (CT) has quickly become a prominent and extremely valuable tool across the Agency for engineering evaluation and inspection of flight hardware.  A current limitation of CT systems; however, is that all scans currently must be performed at room temperature; whereas many of the components that we investigate will experience either cold or hot temperatures during flight.  The objective of the Cryo CT project is to create an environmental test chamber so that reduced temperature CT inspections are possible, down to cryogenic temperatures (liquid N2).  Extended applications of the chamber could also apply to inert gas inspections and future efforts will be focused on adding elevated temperature capability to the system.
