2D Double-MOT System2D + 3D
2D-MOT source chamber + 3D-MOT science cell · one benchtop platform
A benchtop cold-atom system integrating a 2D-MOT source chamber with a 3D-MOT glass science cell. The 2D-MOT continuously loads the science cell with a ≥10⁹ atoms/s cold beam, while differential pumping keeps the science side below 8×10⁻¹⁰ Pa — fast loading and long trap lifetimes at the same time. The unit builds in LinQ's own alkali metal dispenser and miniature combination ion pump: connect your cooling and repump lasers by fiber and a stable cold-atom cloud appears. The glass cell offers open multi-axis optical access — a turnkey platform for quantum-sensor development, atom-interferometer prototyping and cold-atom experiments. For Yb / Sr / K / Ca and other metal species, see the Oven Double-MOT System in the same series.
Key Features
One instrument, the complete chain from atom source to science cell.
Dual-Chamber Architecture
The high-flux 2D-MOT source and the 3D-MOT science cell are separated by differential pumping: high vapor pressure for fast loading on one side, UHV for long trap lifetime on the other.
Glass Science Cell
A large-clear-aperture glass cell gives open multi-axis optical access — convenient for interferometry beams, high-NA imaging and field-coil placement.
LinQ Modules Built In
Alkali metal dispensers (up to 3, Rb / Cs can be mixed) and a miniature combination ion pump are both integrated — LinQ's own modules, validated together at system level.
Plug and Play
Connect cooling and repump lasers by fiber to get a stable cold-atom cloud — no vacuum or optics-building experience required.
Long-Life Vacuum
Holds better than 1×10⁻⁶ Pa for over 60 days without power, so the system can be shipped and moved unpowered. With LinQ's HV power supply running on battery power, the ion pump keeps working without mains electricity, so the system stays movable.
Matching HV Supply
Pair the ion pump with LinQ's HV power supply (ion pump controller) for live vacuum readout and USB / Ethernet remote monitoring.
