Product Description

Product Description

ColdQuanta’s cold atom source cell is a compact vacuum component that simplifies the production of high-flux beams of laser-cooled atoms using 2D or 2D (+) MOTs. The unit is easily integrated into the end user’s vacuum system through a standard CF interface, and is bakeable to 225 °C. Differential pumping of the system is maintained by an aperture in a silicon plate that isolates the user’s vacuum system from the higher pressures required for 2D MOT operation.

The CASC is based on a well-tested design used in ColdQuanta’s RuBECi two-chamber ultrahigh vacuum (UHV) system. Fluxes of several billion atoms-per- second can be achieved with rubidium or cesium.
