Nanoteslameter and Nanovolt-amplifier presented at IMMW19

IMMW19 - 19th International Magnetic Measurement Workshop in Taiwan. Dr. Dragana Popovic Renella presented a novel Nanoteslameter and a Nanovolt-Amplifier. The novel SENIS Nonovolt-Amplifier is an ultra-low noise and offset amplifier for sensitive DC/AC measurements in the range from a few nanovolts to 30µV. The amplifier features the input-referred voltage noise spectral density of 1nV/√Hz and very high linearity. Typical applications of the Nanovolt-amplifier include vibrating wire magnetometry, rotating coil magnetometry, and thermocouple thermometry. The other our latest development is a novel 3-axis Nanotesla-meter for measuring DC/AC magnetic fields in the range from a few nanotesla to 0.1mT. The Teslameter features the noise-equivalent magnetic field spectral density of about 0.1nT/√Hz and sub-millimeter spatial resolution. Typical applications of the Nanotesla-meter include monitoring and active cancelation of environmental magnetic fields, measuring stray magnetic fields of electrical machines, and directional drilling.
