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, miniature combination ion pump and control electronics: connect your cooling and repump lasers by fiber, apply power, 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.
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 dispenser, miniature combination ion pump and HV control supply are all integrated — LinQ's own modules, validated together at system level.
Plug and Play
Connect cooling and repump lasers by fiber and apply power to get a stable cold-atom cloud — no vacuum or optics-building experience required.
Long-Life Vacuum
NEG and combination ion pump maintain the vacuum together — better than 10⁻⁶ Pa for over 60 days without power, so the system ships and moves intact.
Integrated Control
Control electronics and a display are built into the base: magnetic fields, atom source and vacuum status in one view, with USB / Ethernet remote operation.
