Future of neutral atom clocks

Optical Society of America Annual Meeting, 1990
The measurement on energy levels suitable for time standards can be made more precise with the use of neutral atom manipulation techniques. We have created a fountain of atoms where the measurement time of atoms in ballistic free-fall can be on the order

Comment on “Radiation-Belt Remediation Using Space-Based Antennas and Electron Beams” by Carlsten et al.

IEEE Transactions on Plasma Science, 2020
In a recent article, Carlsten et al. state “VLF modes in the ionosphere can be driven either by an antenna or by an electron beam” and dismiss the U.S. Naval Research Laboratory (NRL) concept of producing the very low frequency (VLF) waves by high-speed ...
