Royal Holloway University of London EMP Facilities

The main instruments and support to be made available are:

  • ND1:Nuclear adiabatic demagnetization refrigerator. Equipped with state-of-the-art SQUID based amplifiers. Reconstructed with two enlarged footprints for measurements at 100 µK and 200 µK. Access focused on studies of low dimensional systems, and applications of mechanical resonators, sensor development.

  • ND2:Nuclear adiabatic demagnetization refrigerator. Equipped with state-of-the-art SQUID based amplifiers, 3T high homogeneity NMR magnet. Access focused on topological superfluids, quantum nanofluidics, nanoelectromechanical resonators, thermometry, sensor development.

  • ND3:Nuclear adiabatic demagnetisation refrigerator, equipped with 9T sample magnet. Access focussed on transport measurements, cooling of new materials and nanostructures, nanoelectromechanical resonators, thermometry, strongly correlated quantum matter.

  • ND4:Dry nuclear adiabatic demagnetization refrigerator. Rapid prototyping of experiments down to 0.6 mK. Planned upgrade of magnet system and vibration isolation in collaboration with Oxford Instruments to reduce minimum temperature.

  • Two dry dilution refrigerators with < 10mK base temperature. Access focussed on quantum measurement and metrology.

  • Seven further conventional dilution refrigerators. (i) with sample to-loading facility, to <10 mK (ii) with 3T NMR quality magnet, to < 20 mK (iii) three dilution refrigerators, configured for microwave studies to 20 GHz, focussed on quantum devices and sensors (iv) dilution refrigerator, to < 10mK, with 14 T sample magnet (vi) small dilution refrigerator with 20 mK base temperature, access focussed on SQUID NMR on strongly correlated electron systems.

  • Physical Properties Measurement System (Quantum Design) for materials characterization in magnetic fields < 9T and temperatures >1K.
