11. Development of Time-of-Flight Neutron Depth Profiling at Penn State University
Published: 10/1/2007
Authors: Robert G Downing, S M Cetiner, K Unlu

12. Neutron Collimation With Microchannel Plates: Calibration of Existing Technology and Near
Published: 4/1/2007
Authors: A S Tremsin, Daniel S Hussey, David L Jacobson, Muhammad Arif, Robert G Downing, W B Feller, David F. R. Mildner
Abstract: A new type of high performance and compact neutron collimator can be manufactured from Gd- or B-doped microchannel plates (MCPs). Structures only a few mm thick have very narrow rocking curves and high out-of-angle rejection ratios, as observed previ ...

13. Development of Certified Reference Materials of Ion-Implanted Dopants in Silicon for Calibration of Secondary Ion Mass Spectrometers
Published: 1/1/2007
Authors: David S Simons, Robert G Downing, George Paul Lamaze, Richard Mark Lindstrom, Robert Russ Greenberg, Rick L Paul, Susannah Schiller, William F Guthrie
Abstract: Certified reference materials have been developed for calibration of the concentrations of the most common dopants used in silicon semiconductor technology boron, arsenic, and phosphorus. These materials consist of a single dopant species that is ...
