SQUID current sensors with an integrated thermally actuated input current limiter
Rainer Körber, Patryk Krzysteczko, Monique Klemm +3
The development of SQUID current sensors with a thermally actuated input current limiter (TCL) integrated into the input circuit of the sensor is presented. The TCL is based on an…
Towards ultra-sensitive SQUIDs based on sub-micrometer-sized Josephson Junctions
Jan-Hendrik Storm, Oliver Kieler, Rainer Körber
We recently demonstrated a 1-order axial gradiometer SQUID system, which is operated in a liquid He dewar with negligible noise contribution. The achieved close to…
Evaluating the Performance of Ultra-Low-Field MRI for In-vivo 3D Current Density Imaging of the Human Head
Peter Hömmen, Antti J. Mäkinen, Alexander Hunold +5
Magnetic fields associated with currents flowing in tissue can be measured non-invasively by means of zero-field-encoded ultra-low-field magnetic resonance imaging (ULF MRI) enabli…
Demonstration of full tensor current density imaging using ultra-low field MRI
P. Hömmen, J. -H. Storm, N. Höfner +1
Direct imaging of impressed dc currents inside the head can provide valuable conductivity information, possibly improving electro-magnetic neuroimaging. Ultra-low field magnetic re…
Ultra-sensitive SQUID systems for pulsed fields - Degaussing superconducting pick-up coils
Eva Al-Dabbagh, Jan-Hendrik Storm, Rainer Körber
SQUID systems for ultra-low-field magnetic resonance (ULF MR) feature superconducting pick-up coils which must tolerate exposure to pulsed fields of up to 100 mT. Using type-II sup…
