3D Double-MOT System3D + 3D
3D-MOT source chamber + 3D-MOT science cell · one dual-3D platform
A benchtop cold-atom system integrating a vapor-cell 3D-MOT source chamber with a 3D-MOT glass science cell. The source MOT captures atoms from background vapor and pre-cools them in all three dimensions, then transfers them as slow cold atoms through a differential pumping tube into the science cell — which has no line of sight to the hot vapor source, giving lower background collisions and stray light. Ideal wherever trap lifetime and measurement background matter most. 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. Complementary to our 2D Double-MOT system, the two together cover both high-flux and low-background needs.
Key Features
Pre-cooled in 3D, cleanly transferred — the cleanest atoms delivered to your science cell.
Dual-3D Architecture
Both chambers are full 3D-MOTs: the source side captures and accumulates atoms from vapor with three-dimensional cooling, while the science side traps them in UHV — separated by differential pumping.
Chamber-to-Chamber Cold Transfer
Slow, 3D-pre-cooled atoms travel through the differential pumping tube with high transfer efficiency; no hot source in view means a cleaner measurement background.
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.
