Web9 mrt. 2006 · A 2.45GHz high-current microwave ion source with permanent magnet was developed at Peking University. The source body is about 10cm in diameter and 10cm in height, and its weight is less than 5kg. It can operate in both pulse and continuous wave (cw) modes. In pulse mode, more than 100mA hydrogen ion current was extracted from … Web11 apr. 2024 · However, the sympathetically-cooled ion microwave frequency standard has seldom been studied before. This paper reports the first sympathetically-cooled ion microwave frequency standard in a Paul trap. Using laser-cooled as coolant ions, ion crystal is cooled to below 100 mK and has a coherence lifetime of over 40 s.
