Spin-flip Zeeman slower. Magnetic field profile testing of a spin-flip Zeeman slower for Yb atoms. Yb atoms will travel from right to left through the coils against a counter-propagating 399 nm laser beam.
W+CH4 → WC + 2H2. Quadrupole mass spectrum of tungsten atoms (mass 182-186) and tungsten carbide molecules (mass 194-198) formed by evaporating a tungsten filament in the presence of methane gas.

Ar + W supersonic beam. A tungsten filament is resistively heated to over 3000 K in the presence of an argon buffer gas. The resulting W vapor is entrained in a supersonic jet formed by allowing the argon gas to flow through a nozzle into vacuum. For beam diagnostics, the resulting Ar + W supersonic jet sputters onto copper foils (shown above) placed at various distances downstream.
Yb atomic beam. Ytterbium metal is vaporized in vacuum by running current through a tantalum heating tube (electrical feedthru shown at far left). The atoms are probed with resonant laser light at 399 nm and absorption signals are shown in the inset for Yb atoms in the oven chamber (blue) and trapping chamber (yellow).
