The motion of tracer particles in turbulent superfluid He down to the zero-temperature limit
C. O. Goodwin, M. J. Doyle, J. A. Hay +4
An injection system for polymer particles, with diameters ranging from 1 to 6 m, has been developed for visualizing flows in superfluid He at temperatures down to 0.14 K. Us…
Apparatus to visualize flows in superfluid He below 1 K
I. Skachko, J. A. Hay, C. O. Goodwin +4
We describe a versatile apparatus for optical observations of experimental processes at temperatures down to 0.1 K. The cooling is achieved by a wet cryostat with a dilution refrig…
First Limits on Light Dark Matter Interactions in a Low Threshold Two Channel Athermal Phonon Detector from the TESSERACT Collaboration
C. L. Chang, Y. -Y. Chang, L. Chaplinsky +45
We present results of a search for spin-independent dark matter-nucleon interactions in a 1 cm by 1 mm thick (0.233 gram) high-resolution silicon athermal phonon detector opera…
First Demonstration of the HeRALD Superfluid Helium Detector Concept
R. Anthony-Petersen, A. Biekert, C. L. Chang +33
The SPICE/HeRALD collaboration is performing R&D to enable studies of sub-GeV dark matter models using a variety of target materials. Here we report our recent progress on instrume…
A portable and high intensity 24 keV neutron source based on Sb-Be photoneutrons and an iron filter
A. Biekert, C. Chang, L. Chaplinsky +27
A portable monoenergetic 24 keV neutron source based on the Sb-Be photoneutron reaction and an iron filter has been constructed and characterized. The coincidence of th…
A backing detector for order-keV neutrons
A. Biekert, L. Chaplinsky, C. W. Fink +23
We have designed and tested a large-area (0.15~m) neutron detector based on neutron capture on \ce{^{6}Li}. The neutron detector design has been optimized for the purpose of ta…
Scintillation yield from electronic and nuclear recoils in superfluid He
HeRALD Collaboration, A. Biekert, C. Chang +30
Superfluid He is a promising target material for direct detection of light ( 1 GeV) dark matter. Possible signal channels available for readout in this medium include prompt…
Counting Near Infrared Photons with Microwave Kinetic Inductance Detectors
W. Guo, X. Liu, Y. Wang +8
We demonstrate photon counting at 1550 nm wavelength using microwave kinetic inductance detectors (MKIDs) made from TiN/Ti/TiN trilayer films with superconducting transition temper…
