National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Computed Tomoraphy Analysis of NASA BSTRA Balls.

DE200515011812

Publication Date	2004
Personal Author	Perry, R. L.; Schneberk, D. J.
Page Count	44
Abstract	Fifteen 1.25 inch BSTRA balls were scanned with the high energy computed tomography system at LLNL. This system has a resolution limit of approximately 210 microns. A threshold of 238 microns (two voxels) was used, and no anomalies at or greater than this were observed. At the request of NASA personnel, we performed digital radiography/computed tomography scanning on fifteen BSTRA Balls. All BSTRA Ball specimens were scanned on the same HECAT (high energy computed tomography) system as used for all previous BSTRA scans (some 45 units total). This report addresses the scan of serial numbers 6-92-003 to 6-92-017. This particular system employs a 9 meV LINAC as the x-ray source and a THALES 12 x 16 inch 14-bit Amorphous Silicon panel as the detector.
