Aluminum nuclear demagnetization refrigerator for powerful continuous cooling

Matthias Raba, Sébastien Triqueneaux, James Butterworth +10

Many laboratories routinely cool samples to 10 mK, but relatively few can cool condensed matter below 1 mK. Easy access to the microkelvin range would propel fields such as quantum…

Superconducting aluminum heat switch with 3 n equivalent resistance

James Butterworth, Sébastien Triqueneaux, Šimon Midlik +9

Superconducting heat switches with extremely low normal state resistances are needed for constructing continuous nuclear demagnetization refrigerators with high cooling power. Alum…

Very low resistance Al/Cu joints for use at cryogenic temperatures

Sébastien Triqueneaux, James Butterworth, Johannes Goupy +4

We present two different techniques for achieving low resistance (20 n) contacts between copper and aluminium at cryogenic temperatures. The best method is based on gold…

Design Evaluation of Serial and Parallel sub-mK Continuous Nuclear Demagnetization Refrigerators

D. Schmoranzer, J. Butterworth, S. Triqueneaux +2

We present the evaluation of two different design configurations of a two-stage PrNi continuous nuclear demagnetization refrigerator. Serial and parallel configurations of the…

Discovery of the shape coexisting 0+ state in 32Mg by a two neutron transfer reaction

K. Wimmer, T. Kröll, R. Krücken +36

The Island of Inversion nucleus 32Mg has been studied by a (t,p) two neutron transfer reaction in inverse kinematics at REX-ISOLDE. The shape coexistent excited 0+ state in 32Mg ha…

Measurement of the neutron lifetime using a gravitational trap and a low-temperature Fomblin coating

A. Serebrov, V. Varlamov, A. Kharitonov +9

We present a new value for the neutron lifetime of 878.5 +- 0.7 stat. +- 0.3 syst. This result differs from the world average value (885.7 +- 0.8 s) by 6.5 standard deviations and…
