Use of Kirkpatrick-Baez Multilayer Optics for X-Ring Fluorescence Imaging

July 1, 1998
Author(s)
A S. Bakulin, S M. Durbin, C Liu, J Erdmann, A T. Macrander, Terrence J. Jach
We discuss the possibilities for using Kirkpatrick-Baez (K-B) multilayer elements to directly image the fluorescence distribution from a specimen under x-ray illumination. X-ray fluorescence would be collected by K-B elements close in contrast to the use

Author(s)
William C. Martin, J Sugar, Arlene Musgrove, Craig J. Sansonetti, Jean E. Sansonetti, Edward B. Saloman, V I. Azarov, Alexander Kramida, A N. Ryabtsev, T Shirai
The Atomic Energy Levels Data Center at the National Institute of Standards and Technology (NIST), in cooperation with other laboratories indicated above, is critically evaluating and compiling energy levels, wavelengths, and energy level classifications

Minimization of ion micromotion in a Paul trap

January 1, 1998
Author(s)
D J. Berkeland, J D. Miller, James C. Bergquist, Wayne M. Itano, David J. Wineland
Micromotion of ions in Paul traps has several adverse effects, including alterations of atomic transition line shapes, significatn second-order Doppler shifts in high-accuracy studies and limited confinement time in the absence of cooling. The ac electric

Physics Laboratory - Technical Activities 1997

January 1, 1998
Author(s)
K B. Gebbie, William R. Ott
This report summarizes research projects, measurement method developments, calibration and testing services, and data evaluation activities that were carried out during calendar year 1997 in the NIST Physics Laboratory. These activities are in the areas of

Atomic Physics in Ion Traps

March 1, 1997
Author(s)
C Monroe, John Bollinger
Ion traps allow researchers to control the position and movement of charged particles with exquisite precision, and provide a powerful way to study many atomic phenomena.
