Fully-LabVIEW Powered Mössbauer Spectrometer

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.
