A Coaxial-Resonator Driven rf(Paul)-Trap for Strong Confinement

January 1, 1995
Author(s)
Steven R. Jefferts, C Monroe, E W. Bell, David J. Wineland
We describe a variant of the quadrupole rf (Paul) ion trap capable of localization of a trapped ion to much less than an optical wavelength (Lamb-Dicke regime). The trapping potentials are generated by a high-Q, vacuum-compatible, quarter-wave resonator

A Metrology Approach to Unifying Rockwell C Hardness Scales

January 1, 1995
Author(s)
Jun-Feng Song, J Smith, Theodore V. Vorburger
Current Rockwell C hardness scales (HRC) are unified by performance comparisons. Unless a reliable metrology approach is used for the direct verification of standard hardness machines and diamond indenters, the unified hardness scale may exhibit a

A Production Management Information Model for Discrete Manufacturing

January 1, 1995
Author(s)
Steven R. Ray, S Wallace
The Manufacturing Systems Integration (MSI) project at the National Insitute of Standards and Technology is developing a system architecture that incorporates an integrated production planning and control environment. The development of this architecture
