• Two room temperature spectra measured at once using only one source.
• Increase in the efficiency of utilization of the source by factor of 1.9.
• The detector is mounted on the transducer. The sample is positioned in front of the detector windows.
• In this arrangement the sample is moving while the radioactive source is static.

Two transducers are operated with their own respective radioactive sources, running in different modes. Therefore we have two transmissions setups which can be used either for standard room temperature measurements or used with special experimental equipment, e.g. a furnace, a cryostat, an external magnetic field, reaction chamber or with automatic sample exchangers.

In the emission spectroscopy setup we investigate a sample with incorporated 57Co serving as a source of radiation. The spectrum of the sample is detected using known reference absorber with single line (usually K2Mg57Fe(CN)6).  The setup is similar to that of double spectrometer. This setup allows placing the studied sample to the cryostat or furnace, so we can follow the emission spectra under different conditions.

Also in this case we can also measure two spectra of the same sample simultaneously, thus the time needed for relevant statistics decreases.

The source and detector can be placed also into the backscattering geometry.
