“…While we have presented results for a zirconium neutralizer, currently we are trapping with a yttrium neutralizer. Commercial yttrium is known to degrade the quality of the SC-77 dry-film coating, 26 however, it has neutralized francium reliably in the past. 11…”

We have trapped over 250 000 210 Fr in a new on-line high efficiency magneto-optical trap ͑MOT͒. We describe the new apparatus and present an overview of high-efficiency MOTs for trapping rare isotopes. These traps depend on three critical components: a dry-film coating, a neutralizer, and the optical trap. We have developed a series of independent tests of the effectiveness of these components, and have used the results to construct our trap.

“…Trapping of different isotopes in the same apparatus has been useful for precise measurements of isotopic differences of trapping performance (revealing the precise role of hyperfine changing collisions in a MOT) and mixed-isotope light-assisted collisions in a MOT [1,2]. In addition, multi-isotope ensembles provide near equal mass mixtures of fermionic and bosonic components [3][4][5] and are well suited to sympathetic cooling to lower temperatures because the collision partners have almost equal mass [6,7]. Due to Pauli exclusion, the evaporative cooling of magnetically trapped (i.e.…”

Compact laser cooling apparatus for simultaneous cooling of lithium and rubidium

et al. 2009

We report on a dual species laser cooling apparatus capable of collecting over 10 8 87 Rb or 85 Rb atoms from an atomic vapor or up to (8 ± 2) × 10 7 6 Li atoms directly into a magneto-optic trap (MOT) from an effusive oven without the need for a Zeeman slower. The use of a miniature atomic oven placed close to the trapping region yields a compact vacuum system while still producing adequate lithium ensembles and a high quality vacuum in the 10 −10 Torr range. The atomic sources, laser system, and vacuum system are described. In addition, we use this system to study atom loss from the MOT due to interspecies collisions between 6 Li and 85 Rb or 87 Rb. We report for the first time the heteronuclear loss coefficients for 6 Li-85 Rb mixtures.

“…Since then, numerous investigations, both experimental and theoretical, have been made into the collisional properties of many different homonuclear [2,3,4,5,6,7,8,9,10,11,12,13] and (later) heteronuclear [14,15,16,17,18,19] systems. Collisional studies are in themselves interesting, leading to an in-depth understanding of the various scattering mechanisms present at such low kinetic energies and methods by which we can have some measure of control over elastic and inelastic collisions.…”

Heteronuclear ionizing collisions between laser-cooled metastable helium atoms

et al. 2007

We have investigated cold ionizing heteronuclear collisions in dilute mixtures of metastable (2 3 S1) 3 He and 4 He atoms, extending our previous work on the analogous homonuclear collisions [R. J. W. Stas et al., PRA 73, 032713 (2006)]. A simple theoretical model of such collisions enables us to calculate the heteronuclear ionization rate coefficient, for our quasi-unpolarized gas, in the absence of resonant light (T = 1.2 mK): K (th) 34 = 2.4×10 −10 cm 3 /s. This calculation is supported by a measurement of K34 using magneto-optically trapped mixtures containing about 1×10 8 atoms of each species, K (exp) 34 = 2.5(8)×10 −10 cm 3 /s. Theory and experiment show good agreement.
