Overview

The main task of Magnetic Quality Laboratory is to research in measurement technologies of magnetic qualities, establish and maintain national standards of magnetic qualities. At the present, the lab focuses on research in improvement of reproduction of magnetic flux density.

  • Design of Laser Pumped Helium Magnetometer

    The design replaces discharge lamp by semiconductor laser (laser diode) to improve resolution and accuracy of optically pumped sensor.It will study the possibility of replacing NMR sensor by laser pumped sensor to improve reproduction level of...
