The EDELWEISS Experiment: Status and Outlook

arXiv (Cornell University) (2001)

J. Gascon A. Bonnevaux P. Charvin B. Chambon L. Vagneron

The EDELWEISS Dark Matter search uses low-temperature Ge detectors with heat and ionisation read- out to identify nuclear recoils induced by elastic collisions with WIMPs from the galactic halo. Results from the operation of 70 g and 320 g Ge detectors in the low-background environment of the Modane Underground Laboratory (LSM) are presented.

Stellar and dust emission profiles of IMEGIN galaxies

EPJ Web of Conferences (2024)

Angelos Nersesian R. Adam P. A. R. Ade H. Ajeddig P. André

We present a morphological analysis of a set of spiral galaxies from the NIKA2 Guaranteed Time Large Program, IMEGIN. We have fitted a single Sérsic model on a set of broadband images, from ultra-violet (UV) to millimeter (mm) wavelengths, using the modelling code Statmorph. With the recently acquired NIKA2 1.15- and 2-mm observations, it is possible to extend such a morphological analysis to the mm regime and investigate the two-dimensional (2D) distribution (exponential, Gaussian) of the very cold dust (<15 K). We show preliminary results of the 2D large-scale distribution of stars and dust in spiral galaxies, how they relate to each other, and highlight how they differ from galaxy to galaxy.

High sensitivity magnetization measurements of nanoscale cobalt clusters

Journal of Applied Physics (1995)

Wolfgang Wernsdorfer K. Hasselbach A. Benoı̂t Wolfgang Wernsdorfer B. Barbara

Presented is a novel high sensitivity magnetometer allowing us to measure the magnetization reversal of about 104 μB corresponding to a sensitivity of about 10−16 emu. The detector is a niobium micro-bridge DC superconducting quantum interference device (SQUID), fabricated using electron-beam lithography. It is operational in the temperature range of 0–7 K. Furthermore, we present a method to deposit on the SQUID loop a small number of Co clusters of about 2–5 nm in diameter. The first results obtained on these samples show that there is still a ferromagnetic coupling between the clusters and the magnetization reversal takes place by small avalanches.

Conductance Fluctuations in Disordered Sub-Micron Wires and Rings

Japanese Journal of Applied Physics (1987)

R. A. Webb S. Washburn A. Benoı̂t C. P. Umbach R. B. Laibowitz

A review of the many of the unexpected experimental results obtained over the last three years on the low temperature quantum transport properties of sub-micron normal metal samples is presented. Measurements can now be made on devices where the lithographically patterned distances between measurements probes is much smaller the the characteristic distances over which the conduction electrons maintain their quantum mechanical phase coherence. This in turn has permitted the discoveries of many new quantum interference effects such as the Aharonov-Bohm effect in highly disordered conductors, universal conductance fluctuations, and non-local quantum effects. The ability to vary both the temperature and sample size has yielded information on the effects of averaging these quantum effects over uncorrelated regions and has shown us to some extent how the transition from quantum to a classical system is achieved.

High-speed phonon imaging using frequency-multiplexed kinetic inductance detectors

Applied Physics Letters (2010)

L. J. Swenson A. Cruciani A. Benoı̂t M. Roesch C. S. Yung

We present a measurement of phonon propagation in a silicon wafer utilizing an array of frequency-multiplexed superconducting resonators coupled to a single transmission line. The electronic readout permits fully synchronous array sampling with a per-resonator bandwidth of 1.2 MHz, allowing submicrosecond array imaging. This technological achievement is potentially vital in a variety of low-temperature applications, including single-photon counting, quantum-computing, and dark-matter searches.
