Description
Detailed description of item: Complete cold atomic beam sources for alkaline-earth precision experiments and atomic devices. Small chambers with patented permanent-magnet Zeeman slowers and in-vacuum 2D MOT optics allow high flux with low outgassing and no thermal beam flux at the cold atom port, which provides a CF-133 connection to customer vacuum chamber. Advanced thermal design of the effusion oven allows long-lifetime operation at minimal heating power, with no water cooling. An integrated low-outgassing hot window is provided for coupling of on-axis Zeeman cooling light. Ion and getter pumps integrated into the chamber manage outgassing from the oven at temperatures up to 520 °C. Operating baseline pressures below 1×10-11 mbar can be attained in the customer’s downstream cold atom (typically 3D MOT) science chamber, with suitable pumping speed provided at the differentially-pumped cold beam output port.
