Neutron-based experimental techniques have been continuously improved, refined and
strengthened since the pioneering experiments conducted by Clifford Shull and Bertram …

The bible of gas chromatography-offering everything the professional and the novice need
to know about running, maintaining, and interpreting the results from GC Analytical chemists …

Using a single-phase liquid argon detector with a signal yield of 4.85 photoelectrons per keV
of electronic-equivalent recoil energy (keVee), we measure the scintillation time …

A cryogenic apparatus is described that enables a new experiment, nEDM@ SNS, with a
major improvement in sensitivity compared to the existing limit in the search for a neutron …

The SPICE/HeRALD collaboration is performing research and development to enable
studies of sub-GeV dark matter models using a variety of target materials. Here we report our …

Direct searches for light dark matter particles (mass< 10 GeV) are especially challenging
because of the low energies transferred in elastic scattering to typical heavy nuclear targets …

Ionization of matter by energetic radiation generally causes complex secondary reactions
that are hard to decipher. Using large helium nanodroplets irradiated by extreme ultraviolet …

Molecules immersed in liquid helium are excellent probes of superfluidity. Their electronic,
vibrational, and rotational dynamics provide valuable clues about the superfluid at the …

Tetraphenyl-butadiene is the wavelength shifter most widely used in combination with liquid
argon. The latter emits scintillation photons with a wavelength of 127 nm that need to be …

Dark matter (DM) is one of the most critical questions to be understood and answered in
fundamental physics today. Observations with varied astronomical and cosmological …
