Fluorescence calorimetry of an ion crystal
Marvin Gajewski, Wenbing Li, Sebastian Wolf +5
Motivated by the challenge of identifying intruder ions in a cold ion crystal, we investigate calorimetry from emitted fluorescence light. Under continuous Doppler cooling, the ion…
Development of a Cesium Fountain Clock at HUST: Preliminary Results
Hui Li, Yuanbo Du, Hongli Liu +4
A cesium atomic fountain clock is under development at Huazhong University of Science and Technology (HUST) in China. In this paper, we describe the construction of the entire foun…
Robust Polarization Gradient Cooling of Trapped Ions
Wenbing Li, Sebastian Wolf, Lukas Klein +3
We implement three-dimensional polarization gradient cooling of trapped ions. Counter-propagating laser beams near nm impinge in linlin configuration, at a freque…
A low phase noise microwave source for high performance CPT Rb atomic clock
Xiaodong Li, Peter Yun, Qinglin Li +8
Phase noise of the frequency synthesizer is one of the main limitations to the short-term stability of microwave atomic clocks. In this work, we demonstrated a low-noise, simple-ar…
Development of a recoil ion source providing slow Th ions including Th in a broad charge state distribution
Raphael Haas, Tom Kieck, Dmitry Budker +7
Ions of the isomer Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They…
A simple scheme of low phase noise microwave synthesizers based on the sub-sampling phase lock loop
Wenbing Li, Qiang Hao, Yuanbo Du +3
In this paper, we demonstrate a simple scheme of 6.835 GHz microwave frequency synthesizer based on the sub-sampling phase lock loop (PLL) technique. The application of the sub-sam…
A low phase noise microwave frequency synthesizer based on parameters optimized NLTL for Cs fountain clock
Wenbing Li, Yuanbo Du, Hui Li +1
We report on the development and phase noise performance of a 9.1926 GHz microwave frequency synthesizer to be used as the local oscillator for a Cs fountain clock. It is based on…
