The CASC serves as a source for downstream cold-atom experiments and can be integrated directly into existing ultra-high vacuum systems via a standardized CF connection. The underlying architecture is also used by Infleqtion in its proven two-chamber systems RuBECi and doubleMOT<\/strong> used.<\/p>\n The Cold Atom Source Cell is for the construction of a 2D+ MOT<\/strong> optimized. Laser light and a corresponding magnetic field cool the atoms emerging from the integrated atomic source and form a directed beam of cold atoms.<\/p>\n Typically, atomic fluxes are 1 \u00d7 10\u2079 atoms\/s<\/strong> reached. Depending on the 2D MOT laser parameters used, the longitudinal exit velocity typically lies between 10 and 20 m\/s<\/strong>. The atomic beam has a typical divergence of about 4\u00b0 full angle<\/strong>.<\/p>\n A key feature of CASC is the integrated differential compression stage<\/strong>. A silicon plate with an aperture of 0.75 mm<\/strong> separates the relatively higher operating pressure of the 2D+ MOT from the downstream UHV experiment.<\/p>\n This allows an atomic density suitable for a high atomic flux to be generated in the source cell, while significantly lower pressures can be maintained in the connected science region for long storage and coherence times.<\/p>\n The CASC can with up to two pre-installed alkali atom sources<\/strong> be equipped. Configurations are available for:<\/p>\n This allows the atom source to be adapted to different cold-atom experiments and research platforms.<\/p>\n With dimensions of only 30 \u00d7 30 \u00d7 94.6 mm<\/strong> the CASC has a very compact design. The vacuum connection is made via a standard DN16-CF flange (1.33\u2033)<\/strong>; an adapter plate to 2.75\u2033 is also available.<\/p>\n The construction is without epoxides or glass frits<\/strong> built up and can up to 225 \u00b0C<\/strong> be baked out. This makes the Source Cell suitable for demanding UHV setups in research and quantum technology.<\/p>\n2D+ MOT for high atom fluxes<\/h3>\n
