Performance of a Phonon-Mediated Detector Using KIDs Optimized for Sub-GeV Dark Matter
نویسندگان
چکیده
We provide an update on a gram-scale phonon-mediated KID-based device that was designed for sub-GeV dark matter search at the Northwestern Experimental Underground Site. Currently, is demonstrating 6 eV resolution energy absorbed by resonator. With some important assumptions, this translates to 20 baseline deposited in substrate. show TLS noise dominates estimate. After modifying design mitigate noise, we project 5 substrate (1.5 resonator) amplifier-white-noise-dominated device. Finally, present clear path forward sub-eV resolutions, which includes installation of quantum-limited superconducting parametric amplifier and adjustments material makeup our resonators.

A WIMP Dark Matter Detector Using MKIDs
We are pursuing the development of a phononand ionization-mediated WIMP dark matter detector employing microwave kinetic inductance detectors (MKIDs) in the phonon-sensing channel. Prospective advantages over existing detectors include: improved reconstruction of the phonon signal and event position; simplified readout wiring and cold electronics; and simplified and more reliable fabrication. W...
متن کاملFirst direct detection limits on sub-GeV dark matter from XENON10.
The first direct detection limits on dark matter in the MeV to GeV mass range are presented, using XENON10 data. Such light dark matter can scatter with electrons, causing ionization of atoms in a detector target material and leading to single- or few-electron events. We use 15 kg day of data acquired in 2006 to set limits on the dark-matter-electron scattering cross section. The strongest bou...
متن کاملArDM, a 1t liquid argon detector for dark matter searches
Weak Interacting Massive Particles (WIMPs) are prime candidates for the dark matter in the universe. The ArDM experiment consists of a 1t liquid argon detector to search for WIMPs interacting elastically with argon nuclei. Both scintillation light and ionization charge from nuclear recoils are measured. The 128 nm light is reflected and shifted into the visible range by wavelength shifting foil...
متن کاملA SUPERFLUID He DETECTOR FOR DIRECT DARK MATTER SEARCH
MACHe3 (MAtrix of Cells of superfluid He) is a project of a new detector for direct Dark Matter Search. The idea is to use superfluid He as a sensitive medium. The existing device, the superfluid He cell, will be briefly introduced. Then a description of the MACHe3 project will be presented, in particular the background rejection and the neutralino event rate that may be achieved with such a de...
متن کاملA Superheated Droplet Detector for Dark Matter Search
We discuss the operation principle of a detector based on superheated droplets of Freon-12 and its feasibility for the search of weakly interacting cold dark matter particles. In particular we are interested in a neutralino search experiment in the mass range from 10 to 104 GeV/c2 and with a sensitivity of better than 10−2 events/kg/d. We show that our new proposed detector can be operated at a...
