Determining cleanliness levels along the neutron tube manufacturing line

PDF Version Also Available for Download.

Description

A study is underway to identify a rapid, easy method for determining cleanliness levels during the manufacture of neutron tubes. Due to high reliability concerns associated with neutron tubes, cleanliness levels of metal and ceramic piece parts are critical. Sandia has traditionally used quantitative surface analytical methods, such as Auger Electron Spectroscopy and X-ray Photoelectron Spectroscopy for determining cleanliness levels. A critical disadvantage of these techniques is the time required to perform them. More rapid, reliable methods are needed for in-line testing of neutron tube assemblies. Several methods including contact angle, MESERAN, Fourier Transform Infrared Spectroscopy, and Optically Stimulated Electron ... continued below

Due to high reliability concerns associated with neutron tubes, cleanliness levels of metal and ceramic piece parts are critical. Sandia has traditionally used quantitative surface analytical methods, such as Auger Electron Spectroscopy and X-ray Photoelectron Spectroscopy for determining cleanliness levels. A critical disadvantage of these techniques is the time required to perform them. More rapid, reliable methods are needed for in-line testing of neutron tube assemblies. Several methods including contact angle, MESERAN, Fourier Transform Infrared Spectroscopy, and Optically Stimulated Electron Emission measurements are being evaluated as potential candidates. Cleanliness levels for each of these methods have been compared to Auger Electron Spectroscopy results, after processing samples through similar test conditions. An attempt was made to correlate the results from the alternative methods to those of Auger Electron Spectroscopy. Test results are presented.
