US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
An experiment to search for dark matter interactions using sodium iodide detectors
Govinda Adhikari, Pushparaj Adhikari, Estella Barbosa de Souza +47
Observations of galaxies and primordial radiation suggest that the Universe is made mostly of non-luminous dark matter. Several types of new fundamental particles have been propose…
Single photon performance characterisation of a Generation I Large Area Picosecond PhotoDetector
Robert Foster, Andrew Scarff, Matthew Malek
The single photoelectron performance characteristics of a Large Area Picosecond PhotoDetector (LAPPD) were studied using a picosecond optical laser source. We verify that the LAPPD…
Reducing DRIFT Backgrounds with a Submicron Aluminized-Mylar Cathode
James B. R. Battat, Ed Daw, Alexei Dorofeev +22
Background events in the DRIFT-IId dark matter detector, mimicking potential WIMP signals, are predominantly caused by alpha decays on the central cathode in which the alpha partic…
Background Assay and Rejection in DRIFT
Jeff Brack, Ed Daw, Alexei Dorofeev +22
The DRIFT-IId dark matter detector is a m-scale low-pressure TPC with directional sensitivity to WIMP-induced nuclear recoils. Its primary backgrounds were due to alpha decays…
PocketWATCH: Design and operation of a multi-use test bed for water Cherenkov detector components in pure and gadolinium loaded water
Matthew Thiesse, Stephen T. Wilson, Jack Fannon +4
The PocketWATCH facility is a unique multi-purpose test bed designed to replicate the conditions of large water Cherenkov detectors. Housed at the University of Sheffield, the faci…
Energy Loss Due to Defect Formation from Pb Recoils in SuperCDMS Germanium Detectors
Robert Agnese, Taylor Aralis, Tsuguo Aramaki +94
The Super Cryogenic Dark Matter Search experiment (SuperCDMS) at the Soudan Underground Laboratory studied energy loss associated with Frenkel defect formation in germanium crystal…
Characterisation of the Temperature-dependent Dark Rate of Hamamatsu R7081-100 10" Photomultiplier Tubes
Steve T. Wilson, Samuel Fargher, Robert J. Foster +4
Dark noise is a dominant background in photomultiplier tubes (PMTs), which are commonly used in liquid-filled particle detectors for single-photon detection to see the results of p…
