Abstract

The invention relates to a miniature magnetic spectrometer with a coaxial structure. This spectrometer, associated with a particle generator, comprises a transformer producing a magnetic field for deflecting the charged particles injected at one end of the spectrometer body. The transformer is provided with a secondary circuit, constituting the spectrometer body, formed by an external conductor in short-circuit with an internal conductor and coaxial to the external conductor. These two conductors define an annular space in which can move the charged particles. Means for detecting the deflected particles, disposed at a second end of the spectrometer body, means for selecting the particles in accordance with their injected angle and a converter element for the particles placed in the annular space level with the first end also being provided.
