Metrology, biomagnetics, environment surveillance

One of the main goals of the research program with the title Metrology, biomagnetics, environment surveillance is to establish the national standard for the magnetic flux density and to get the laboratory for magnetic measurements accredited for the measurements of this quantity. In the past few years the laboratory for magnetic measurements (LMM) cooperates with the German institute Physikalisch-Technishe Bundesanstalt (PTB) from Braunschweig in the field of precision magnetic measurements. PTB is also the reference laboratory which keeps the magnetic flux primary standard. In this cooperation a magnetometer based on nuclear magnetic resonance (NMR) and some reference coils were developed to be used as the national standard. Improvements of the existing magnetometer (wider measuring range and higher speed) and production and calibration of more reference coils are planned. At the same time our lab is involved in the process of accreditation at German calibration service Deutscher Kalibrierdienst (DKD) to become the first accredited laboratory in this field in Slovenia. The work on development of reference sources for energizing the coils for magnetic field generation is based on our previous and present research of digital sine voltage and phase generators. Namely, a phase source is needed for generation of two or three-dimensional rotating magnetic field. Another area of research in our laboratory is biological effects of weak magnetic fields to living organisms. The goal is to determine the highest safe level of magnetic field in living and working environments. This can only be done through practical experiments and using the appropriate measuring equipment, which we have. We are also dealing with the measurements regarding environment protection i.e. parameters of living and working environment. This includes research of different kinds of sensors and measurement methods using these sensors.
