Probing the Dark Matter EFT with QUEST-DMC: Projected Sensitivities and Attenuation Ceilings
DMC Collaboration, N. Darvishi, S. Autti +27
This proceedings contribution summarises projected constraints from the QUEST-DMC concept, a surface-based direct-detection experiment using superfluid He operated below the mi…
Characterisation of silicon photomultipliers in a dilution refrigerator down to 9.4 mK towards a cryogenic cosmic-ray muon veto system
DMC Collaboration, A. Kemp, S. Autti +30
We report the characterisation of a FBK NUV-HD-cryo silicon photomultiplier (SiPM) sensor operated in a 9.4 0.2 mK environment inside a dilution refrigerator, towards the dev…
Development of superfluid helium-3 bolometry using nanowire resonators with SQUID readout for the QUEST-DMC experiment
DMC Collaboration, E. Leason, L. V. Levitin +28
Superfluid helium-3 bolometers can be utilised for dark matter direct detection searches. The extremely low heat capacity of the B phase of the superfluid helium-3 at ultra-low tem…
Dark Matter EFT Landscape Probed by QUEST-DMC
DMC Collaboration, N. Darvishi, S. Autti +27
We present the projected sensitivity to non-relativistic Effective Field Theory (EFT) operators for Dark Matter (DM) direct detection using the QUEST-DMC experiment. QUEST-DMC empl…
Dark Matter Attenuation Effects: Sensitivity Ceilings for Spin-Dependent and Spin-Independent Interactions
DMC Collaboration, N. Darvishi, J. Smirnov +27
Direct detection experiments aimed at uncovering the elusive nature of dark matter (DM) have made significant progress in probing ever lower cross-sections for DM-nucleon interacti…
Drag on Cylinders Moving in Superfluid 3He-B as the Dimension Spans the Coherence Length
S. Autti, R. P. Haley, A. Jennings +4
Vibrating probes when immersed in a fluid can provide powerful tools for characterising the surrounding medium. In superfluid 3He-B, a condensate of Cooper pairs, the dissipation a…
QUEST-DMC: Background Modelling and Resulting Heat Deposit for a Superfluid Helium-3 Bolometer
S. Autti, A. Casey, N. Eng +21
We report the results of radioactivity assays and heat leak calculations for a range of common cryogenic materials, considered for use in the QUEST-DMC superfluid 3He dark matter d…
QUEST-DMC superfluid He detector for sub-GeV dark matter
S. Autti, A. Casey, N. Eng +22
The focus of dark matter searches to date has been on Weakly Interacting Massive Particles (WIMPs) in the GeV/-TeV/ mass range. The direct, indirect and collider searches…
Thermal transport in nanoelectronic devices cooled by on-chip magnetic refrigeration
S. Autti, F. C. Bettsworth, K. Grigoras +8
On-chip demagnetization refrigeration has recently emerged as a powerful tool for reaching microkelvin electron temperatures in nanoscale structures. The relative importance of coo…
Microkelvin thermometry with Bose-Einstein condensates of magnons and applications to studies of the AB interface in superfluid He
P. J. Heikkinen, S. Autti, V. B. Eltsov +2
Coherent precession of trapped Bose-Einstein condensates of magnons is a sensitive probe for magnetic relaxation processes in superfluid 3He-B down to the lowest achievable tempera…
