A module is described having a magnetic shielding enclosure composed of a pedestal and of a housing unit. The housing unit has an electromagnetic cavity to create a radiofrequency field and a plurality of electrical conductors arranged to form a solenoid. The beam of particles passes through the shielding enclosure through two apertures provided in the entry and exit plates. The electrical conductors are arranged in a symmetrical manner in relation to a plane parallel to the plane of the coils and containing the beam of particles. A very homogenous, constant magnetic field results. The module can be used in atomic or molecular beam resonators.
