Neutron Irradiation to Increase the C-Axis Compressive Strength of Sapphire at Elevated Temperature

February 29, 2000
Author(s)
T M. Regan, D C. Harris, D W. Blodgett, K C. Baldwin, J A. Miragliotta, M E. Thomas, M J. Linevsky, J W. Giles, R M. Stroud, T A. Kennedy, M Fatemi, David R. Black
Neutron irradiation of sapphire with 1 x 10 18 neutrons (≥ 1 MeV)/cm 2 increases the c-axis compressive strength by a factor of 3 at 600 C. The mechanism of strength enhancement is the retardation of r-plane twin propagation by radiation-induced defects

GLUT/Tk: Open GL with Tcl/Tk

May 1, 2003
Author(s)
Joseph Konczal
GLUT/Tk provides a mechanism for control of 3D graphics applications by a full-featured GUI system. It connects control windows written in Tk to OpenGL graphics windows managed by GLUT, with minimal disruption of each package's default program structure

Combinatorial Coverage Measurement

October 26, 2012
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
Combinatorial testing applies factor covering arrays to test all t-way combinations of input or configuration state space. In some testing situations, it is not practical to use covering arrays, but any set of tests covers at least some portion of t-way

Robust infrared filters for x-ray spectroscopy

March 11, 2004
Author(s)
Nathan A. Tomlin, Joel Ullom, James A. Beall, Gene C. Hilton, Steven Deiker, W.Bertrand (Randy) Doriese, Kent D. Irwin, Carl D. Reintsema, Leila R. Vale, Yizi Xu
One challenge to using cryogenic detectors for x-ray spectroscopy on a scanning electron microscope is the implementation of infrared blocking filters. In order to achieve high x-ray transmission, these filters can be as thin as 250 nm and consequently are
