Presentation
Our group at Northwestern recently demonstrated the world's first
scintillating bubble chamber, observing simultaneous scintillation and
bubble nucleation by nuclear recoils in superheated liquid xenon
(arXiv:1702.08861). These detectors already promise unmatched
background rejection in searches for canonical WIMP dark matter, and we
are beginning to explore the low-threshold (<=1 keV...

Presentation
Next generation liquid xenon TPCs are poised to increase our sensitivity to dark matter by more than an order of magnitude over a wide range of possible dark matter candidates. In this talk I will describe an idea to expand the reach and flexibility of such detectors even further, by adding helium and neon to the xenon to enable searches for very light dark matter and combining high and low Z...

Light/charge response in Noble Elements (gas, liquid, dual phase)
Presentation
We report the results of an experiment which collected scintillation light induced by cosmic ray muons in xenon-doped liquid argon within the Blanche cryostat at Fermilab. Doping the liquid argon with xenon at concentrations of 7 ppm and greater resulted in a two-fold increase in the amount of scintillation photons incident on the detectors. Examination of the time-resolved scintillation...

Light/charge response in Noble Elements (gas, liquid, dual phase)
Presentation
Electron- and ion-beam induced emission spectra of argon and argon-xenon mixtures were studied. A wide wavelength range from the vacuum ultraviolet (VUV) to the near infrared (IR) was covered (115nm – 3500nm). An intense emission at a peak wavelength of 1.173 µm has been discovered in a mixture of 10ppm xenon in liquid argon which can be of interest for detector development. The well-known 127...

Applications (dark matter, neutrino, precision frontier, medicine, etc.)
Presentation
Superfluid helium has many merits as a detector target material to probe sub-GeV dark matter, including good kinematic matching with light dark matter, excellent intrinsic radiopurity, and ability to be cooled down to milli-Kelvin temperature to enable phonon readout using transition edge sensor. At the same time, this uniform liquid may be used to make a monolithic detector. We propose to...
