A device for generating and manpulating coherent matter waves contains a magnetic trap being adapted to form a magnetic trapping potential for gas atoms, said magnetic trap comprising a plurality of trap coils being connected with a current supply device and including two quadrupole coils and one Ioffe coil, wherein the trap coils are arranged in such a relative position that a common trap is formed, said common trap having a quadrupole trap shape with one trap minimum if the quadrupole coils are in an operation condition and the Ioffe coil is in a currentless condition or two trap minima or a Ioffe trap shape if all the quadrupole and Ioffe coils are in an operation condition and a shielding device protecting the magnetic trap against external magnetic fields. A method of continuous extracting matter waves from the trap is described.
