Miniaturized Cold-Atom System for Continuous Operation
Here’s PatSnap Eureka !
Summary
Problems
Conventional ultracold matter systems are large, costly, and poorly suited for applications requiring small size, low weight, and low power consumption due to their multi-chamber vacuum systems and periodic reloading of vacuum with atoms, which prevents continuous operation.
Innovation solutions
A multichamber Bose-Einstein-condensate vacuum system with interconnected vacuum chambers via microchannels, including an atom source and an atom chip, with a mechanism for transporting atoms using magnetic motors and optical illumination, and a frame compatible with temperature changes, enabling miniaturization and continuous operation.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If conventional multi-chamber vacuum systems are used, then ultrahigh vacuum can be achieved, but the system size and weight increase significantly
Why choose this principle:
The patent combines multiple vacuum chambers into a single integrated chamber, eliminating the need for separate multi-chamber systems. The atom chip apparatus includes integrated regions for atom generation, trapping, and experimentation within one vacuum environment, reducing overall system weight while maintaining ultrahigh vacuum conditions through unified vacuum pumping.
Principle concept:
If conventional multi-chamber vacuum systems are used, then ultrahigh vacuum can be achieved, but the system size and weight increase significantly
Why choose this principle:
The single vacuum chamber serves multiple functions simultaneously: it houses the atom source, magnetic traps for cooling and trapping atoms, optical access regions for laser manipulation, and experimental areas for atom chip operations. This multi-functional integration eliminates the need for separate specialized chambers while achieving the same scientific objectives.

Abstract
A cold-atom system has multiple vacuum chambers. One vacuum chamber includes an atom source. A fluidic connection is provided between that vacuum chamber and another vacuum chamber. The fluidic connection includes a microchannel formed as a groove in a substantially flat surface and covered by a layer of material.
