Abstract:
1. A resonator assembly for executing measurements on a sample within a constant magnetic field B 0 by means of magnetic resonance, comprising a resonator portion defining a longitudinal axis and an axial direction, said resonator portion having along said axial direction a hollow cavity for exciting electron resonance within said sample, and a coupling portion adjacent said resonator portion in said axial direction, said resonator portion being provided in said direction of said longitudinal axis with a stepped through being electrically conductive at its inner surface, a first, middle section of said stepped through configuring said hollow cavity, and a second and a third, lateral section of said stepped through adjacent axially opposed sides of said hollow cavity being each dimensioned such that a basic mode being resonant within said hollow cavity is unable to propagate within said second and said third section, wherein means are provided for additionally exciting a nuclear resonance within said sample, said means being configured as a coil wound around said resonator portion, said resonator portion comprising a toroidal body made from an electrically conductive material within which there is provided said stepped through, and that said toroidal body is provided with at least one axial slit.
