Draft:OLTWINS

From Wikipedia, the free encyclopedia

OLTWINS is the name of a family of Mössbauer spectrometers developed at the Department of Experimental Physics, Faculty of Science, Palacký University Olomouc. The family ranges from compact single-channel instruments to custom and multichannel systems. Its TenBeam and SixBeam configurations are designed to record several spectra simultaneously using a common radioactive source, with up to ten and six measurement positions, respectively.[1]

The instruments combine programmable transducer control with detector signal acquisition and can be configured for transmission spectroscopy, conversion electron Mössbauer spectroscopy (CEMS), conversion X-ray Mössbauer spectroscopy (CXMS), coincidence measurements and time-differential Mössbauer spectroscopy. A dual-channel version described in 2023 uses a microcontroller and an FPGA for transducer control and signal processing.[2] OLTWINS spectrometers have been used in the development of scintillation detectors and focusing optics,[3][4] as well as in studies of iron oxalates and iron-containing nanocomposites.[5][6]
