Trapping and laser cooling of trace Ca+ isotopes injected from an inductively coupled plasma mass spectrometer

Dynamics of ion loading into a linear Paul trap using an inductively coupled plasma mass spectrometer

“…15 Each laser frequency is monitored using a wavemeter and a temperature stabilized Fabry-Pérot interferometer (FPI) with a free spectrum range (FSR) of 1 GHz. For 43 Ca + , another 397 nm laser radiation is required for the transition corresponding to the hyperne levels.…”

“…The apparatus has been explained in ref. 15. The setup consists of ICP-MS with a reaction cell (Dynamic Reaction Cell; DRC), ion optics, a segmented linear Paul trap, an observation system and lasers.…”

“…Laser cooling of Ca + is realized [10][11][12][13][14][15] by using the 397 nm and 866 nm radiation of external cavity diode lasers (ECDLs), corresponding to the transitions of 4S 1/2 to 4P 1/2 and 3D 3/2 to 4P 1/2 , 15 respectively. For 43 Ca + , another 397 nm laser radiation is required for the transition corresponding to the hyperne levels.…”

“…For 43 Ca + , another 397 nm laser radiation is required for the transition corresponding to the hyperne levels. 15 Each laser frequency is monitored using a wavemeter and a temperature stabilized Fabry-Pérot interferometer (FPI) with a free spectrum range (FSR) of 1 GHz. They are tuned to the resonances of the target isotope whose optical isotope shis of the transition wavelengths are presented in Table 1.…”

All-diode-laser cooling of Sr+isotope ions for analytical applications

“…In order to investigate the possibilities of the methodology, we have developed a novel apparatus combining an ICP-MS and an ion trap. 11) In this apparatus, an ICP-MS is used as an ion source in order to realize continuous feeding of massto-charge selected target ions from a liquid sample outside of the vacuum chamber. Mass-separated ions by ICP-MS are trapped in a linear Paul trap.…”
