Abstract
The virtual instrumentation techniques are applied for the first fully-LabVIEW powered Mössbauer spectrometer. The spectrometer application has to carry out several different tasks such as gamma-ray pulse height analysis (via digital oscilloscope), reference velocity signal generation for the motion of the radioactive source (via function generator) together with digital proportional-integral-derivative (PID) unit responsible to control the relative precise velocity between the source and the absorber (via CompactRIO) and Mössbauer spectra accumulation.
Highlights
A plenty of different programming techniques and instrument solutions are used in the development of Mössbauer spectrometers [1,2,3]
A new design of Mössbauer spectrometer uses the virtual instrumentation techniques [4,5,6] and it is based on commercially available USB, PCI or PXI devices
The LabVIEW software flexibility allows the wide number of hardware combinations that could provide required function
Summary
A plenty of different programming techniques and instrument solutions are used in the development of Mössbauer spectrometers [1,2,3]. Mössbauer spectroscopy represents an essential tool for the investigation of specific elements-containing materials (Fe, Sn, Au ...) as its local probing capability. It allows to determine and quantify different atomic surrounding, magnetic states and in-field magnetic arrangements of magnetic moments, conveying structural and magnetic information, superior in comparison with other experimental techniques [1,2,3]. The Mössbauer spectrum is dependency between radioactive source velocity and the detected γ-ray intensity. This experimental technique is a frequently used tool in many areas of research such as physics, chemistry, biology, metallurgy etc
