Versatile Zeeman slower CsYb data

We describe the design, construction and operation of a versatile dual-species Zeeman slower for
both Cs and Yb, which is easily adaptable for use with other alkali metals and alkaline earths. With
the aid of analytic models and numerical simulation of decelerator action, we highlight several real-world
problems affecting the performance of a slower and discuss effective solutions. To capture Yb
into a magneto-optical trap (MOT), we use the broad 1S0 to 1P1 transition at 399 nm for the slower
and the narrow 1S0 to 3P1 intercombination line at 556 nm for the MOT. The Cs MOT and slower
both use the D2 line (62S1/2 to 62P3/2) at 852 nm. We demonstrate that within a few seconds the
Zeeman slower loads more than 10^9 Yb atoms and 10^8 Cs atoms into their respective MOTs. These
are ideal starting numbers for further experiments on ultracold mixtures and molecules.
