Abstract
A microwave interaction module has a magnetic shield in which is created a constant magnetic field (the 'C field'), an an electromagnetic cavity for generating a radiofrequency magnetic field in the path of beam of atomic or molecular particles. The electromagnetic cavity comprises a first U-shaped wave-guide, the extremities of which are provided with apertures for the passage of the beam of particles, and a second wave-guide connected electromagnetically to the first wave-guide by a connecting aperture made in the upper face of the first wave-guide. The entire electromagnetic cavity is thus within the magnetic sield and the radiofrequency signal is carried by a coaxial cable passing through this shield.
