78. The SENSEI Experiment: An Ultrasensitive Search for Sub-GeV Dark Matter

Mr Mariano Cababie (University of Buenos Aires / Fermilab National Accelerator Laboratory)

7/20/20, 1:00 PM

Devices with low energy thresholds are one of the main pillars for the direct detection of dark matter, and tremendous progress has been made in the past few years in probing dark matter with sub-GeV masses. The SENSEI (Sub-Electron Noise Skipper Experimental Instrument) Collaboration has pioneered the silicon-based Skipper-Charge Coupled Device (CCD) technology capable of detecting electron...

36. NEXUS@FNAL Status and Plans

Nicholas Mast

7/20/20, 1:15 PM

The Northwestern EXperimental Underground Site at Fermilab (NEXUS@FNAL) is an underground cryogenic detector testing facility located in a clean room near the NOVA near detector. It currently features a vibration-isolated dry dilution refrigerator which operates down to 10 mK. The 300 meter water equivalent depth, combined with lead shielding around the refrigerator, is expected to lead to a...

86. Tuning the axion radio with Axion Dark Matter eXperiment (ADMX)

Rakshya Khatiwada

7/20/20, 1:30 PM

An overview of the most sensitive experiment to probe the QCD axion to date. In particular, it will focus on ADMX's recent success in reaching the so-called DFSZ sensitivity—a decade long goal sought by axion experimenters -- and its newest limits covering axion mass ranges of 2.66 to 3.31 μeV. Last but not least, a brief discussion of its recent technological advancements will follow.

83. The DarkSide-20k Experiment in 10 Minutes

Michael Poehlmann (University of California, Davis)

7/20/20, 1:45 PM

DarkSide-20k is a next-generation dark matter detector at the Laboratori Nazionali del Gran Sasso in Italy. With a projected sensitivity of $7.4 \times 10^{−48}$ cm$^2$ for 1 TeV/$c^2$ WIMPs for a 10 year run, DarkSide-20k will be the most sensitive dark matter experiment ever built. I will highlight the innovative design features of the DarkSide-20k experiment, including custom cryogenic...

11. Constraints on Dark Matter Microphysics from Dwarf Galaxies

Ethan Nadler (Stanford/KIPAC)

7/20/20, 2:00 PM

As luminous tracers of the smallest halos, dwarf galaxies offer a unique window into the physics of dark matter (DM). The (lack of) a cutoff in the abundance of low-mass halos informs a variety of DM properties, which is crucial given the breadth of theoretical models that have gained popularity following the search for canonical WIMPs. In this talk, we describe recent advances in measuring...
