Ball-grid array architecture for microfabricated ion traps
Nicholas D. Guise, Spencer D. Fallek, Kelly E. Stevens +11
State-of-the-art microfabricated ion traps for quantum information research are approaching nearly one hundred control electrodes. We report here on the development and testing of…
Measurement of the Kr XVIII 3d lifetime at low energy in a unitary Penning trap
Nicholas D. Guise, Joseph N. Tan, Samuel M. Brewer +2
A different technique is used to study the radiative decay of a metastable state in multiply ionized atoms. With use of a unitary Penning trap to selectively capture Kr ion…
Capture and isolation of highly-charged ions in a unitary Penning trap
Samuel M Brewer, Nicholas D Guise, Joseph N Tan
We recently used a compact Penning trap to capture and isolate highly-charged ions extracted from an electron beam ion trap (EBIT) at the National Institute of Standards and Techno…
Highly Charged Ions in Rare Earth Permanent Magnet Penning Traps
Nicholas D. Guise, Samuel M. Brewer, Joseph N. Tan
A newly constructed apparatus at the National Institute of Standards and Technology (NIST) is designed for the isolation, manipulation, and study of highly charged ions. Highly cha…
Self-Excitation and Feedback Cooling of an Isolated Proton
N. Guise, J. DiSciacca, G. Gabrielse
The first one-proton self-excited oscillator (SEO) and one-proton feedback cooling are demonstrated. In a Penning trap with a large magnetic gradient, the SEO frequency is resolved…
