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…
Voltage Noise Thermometry in Integrated Circuits at Millikelvin Temperatures
G. Ridgard, M. Thompson, L. Schreckenberg +5
This paper demonstrates the use of voltage noise thermometry, with a cross-correlation technique, as a dissipation-free method of thermometry inside a CMOS integrated circuit (IC).…
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…
On-chip quantum confinement refrigeration overcoming electron-phonon heat leaks
S. Autti, J. R. Prance, M. Prunnila
Circuit-based quantum devices rely on keeping electrons at millikelvin temperatures. Improved coherence and sensitivity as well as discovering new physical phenomena motivate pursu…
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…
Non-galvanic calibration and operation of a quantum dot thermometer
J. M. A. Chawner, S. Barraud, M. F. Gonzalez-Zalba +4
A cryogenic quantum dot thermometer is calibrated and operated using only a single non-galvanic gate connection. The thermometer is probed with radio-frequency reflectometry and ca…
