Spin-Polarized Photoemission Spectroscopy of Magnetic Surfaces Using Undulator Radiation

January 1, 1992
Author(s)
Philip Johnson, S Hulbert, R Klaffky, N Brookes, Andrew Clarke, B Sinkovic, N. Smith, Robert Celotta, Michael H. Kelley, Daniel T. Pierce, M Scheinfein, B Waclawski, B.O. Wells
A beamline has been established at the National Synchrotron Light Source to perform angle-resolved photoemission experiments on magnetic surfaces with spin sensitivity. The system has two novel features: it uses a miniature electron-spin polarization

Transfer function approach to the experimental determination of mode transfer matrices

July 20, 1990
Author(s)
Shao Yang, Igor Vayshenker, D. R. Hjelme, I. P. Januar, A. R. Mickelson
An improved scheme for characterization of multimode fiber systems is investigated. Characterization with transfer matrices requires multiple measurements for each component. The transfer function approach herein investigated requires only a single launch

Transfer function analysis of measured transfer matrices

August 1, 1989
Author(s)
Shao Yang, Igor Vayshenker, A. R. Mickelson
Measurements of mode transfer matrices of various multimode fiber optic connectors are presented. To analyze the accuracy and repeatability of such measurements, a theoretical framework which employs mode transmission functions is derived. It is shown that

Improved Low-Energy Diffuse Scattering Electron-Spin Polarization Analyzer

January 1, 1989
Author(s)
M Scheinfein, Daniel T. Pierce, John Unguris, Jabez J. McClelland, Robert Celotta, Michael H. Kelley
An improved low-energy diffuse scattering electron-spin polarization analyzer is described. It is based on the low-energy (150 eV) diffuse scattering of polarized electrons from polycrystalline evaporated Au targets. By collecting large solid angles and
