Mössbauer spectrometer with resonant detector

A Mössbauer spectrometer with a collective synchronous motion of the radioactive source and resonant detector has been built. The new special transducer with four drive coils and one velocity pickup coil has been developed. The drive coils are distributed over a perimeter of the moving frame, which connects the source and resonant detector. This configuration ensures an effective suppression of any mechanical vibrations and excitations in the moving frame. The polyamide fibers serve as suspension brackets, barium ferrite magnets are used. The mechanical construction of the transducer allows the use of various cryostats and furnaces, because the sample is immovable. The spectrometer developed provides an effective application of resonant detectors in a wide range of absorber temperatures.
