A cold atom beam generating device with a replaceable atomic source

Abstract

The application belongs to the technical field of cold atom beam preparation equipment, and discloses a cold atom beam generating device capable of quickly replacing an atom source, which comprises a vacuum optical cavity, which is a hollow cavity and is provided with at least one connecting port; an atom source module, which is arranged in the vacuum optical cavity and is detachably connected with the connecting port of the vacuum optical cavity; and a port function module, which is detachably and sealingly connected with the connecting port of the vacuum optical cavity. Through modular structures such as a differential flange, an electrode flange and a rotating wheel base, when the atom source is exhausted, the user does not need to rely on the original equipment manufacturer to disassemble, but can operate by himself / herself, only needs to disassemble and replace the atom source module at the electrode flange port, changes the maintenance mode that must be intervened by professional personnel, improves the convenience of equipment maintenance, reduces the system downtime from several days or even several weeks required by the traditional scheme, and improves the service continuity and operation efficiency of the equipment.
