Mössbauer spectrometer
Renon's new generation MS-4 digital Mössbauer spectrometer includes a radiation detection block including a detection head, a nuclear block, and vibrator control and system control blocks. It is equipped with a laser source movement speed calibrator. The spectrometer's detection head includes an integrated preamplifier and high-voltage power supply. The nuclear block enables the simultaneous analysis of four spectra: two Mössbauer spectra and γ amplitude spectra collected in the coincidence and anticoincidence modes with the window of a single-channel analyzer. One of the spectra can be replaced by data from a laser speed calibrator.

Investigation of local electronic (oxidation state), structural (electric field gradient) and magnetic (ordering temperatures, anisotropy, internal magnetic field) properties of samples containing Fe, Sn or Eu compounds. Quantifying the composition of multiphase samples and estimating the average size of iron-based nanoparticles. Investigation of submicron-thick layers using conversion electron sensing technique (CEMS).
Układ spektrometru jest wyposażony w z zalewowy kriostat helowy (firmy IceOxford), umożliwiający pomiary w zakresie temperatur 1.5÷300 K. Chłodzony wodą próżniowy piecyk mӧssbauerowski firmy Elektronika Jądrowa pozwala na pomiary w zakresie temperatur od 300K do 1100 K. Zakres prędkości wibratora: od ±0.5 do ±150 mm/s
