Abstract
A specimen head for electron spin resonance and paramagnetic electron resonance measurements, having an annularly cylindrical resonator, with a waveguide being coupled to one of its end walls in such a manner as to excite an H.sub.011 wave. The other end wall is formed by a piston capable of being shifted for tuning, the piston being attached at the end of a hollow piston rod (6) mounted in a bearing block (4), which also contains the resonator (16), in such a manner that it is concentric relative to the axis of the resonator and longitudinally shiftable. The waveguide (13) is attached to the bearing block (4) on that side of the resonator (16) which is opposite the piston (7) and extends along the outside of the bearing block parallel to the piston rod (6) after having been deflected 180.degree.. Drive shafts (24, 34) for means for shifting the piston (7) and means for altering the coupling of the waveguide (13) are arranged on that side of the piston rod (6) opposite the waveguide (13) in the plane containing the axes of the waveguide and the piston rod (6) and are mounted in or on the bearing block (4). The bearing block (4) is attached to a head member (1) by means of rods (3) …
