Corrections to Signal Saturation on the DEAP-3600 Dark Matter Search
Dark matter is currently a topic at the frontier of astroparticle physics research. Its discovery or refutation would have profound implications for particle physics, cosmology, and astrophysics. There are numerous experiments ... -
Measurement of Cosmogenic Production Rates in Ge with CDMSlite
The majority of matter in the Universe is non-luminous, non-baryonic, and as of yet undiscovered. The SuperCDMS experiment searches for this "dark matter" in the form of Weakly Interacting Massive Particles (WIMPs), operating ... -
A Modified Detector Concept for SuperCDMS: The HiZIP and Its Charge Performance
(2013-10-03)SuperCDMS is a leading direct dark matter search experiment which uses solid state detectors (Ge crystals) at milliKelvin temperatures to look for nuclear recoils caused by dark matter interactions in the detector. ‘Weakly ... -
A New and Improved Spin-Dependent Dark Matter Exclusion Limit Using the PICASSO Experiment
(2009-11-18)The PICASSO project is a direct dark matter search experiment located 2070 metres underground in SNOLAB. Superheated droplets of Freon (C4F10) are used as the active mass, providing a target for the incoming neutralinos. ... -
The PICO Dark Matter Search: Reflections and Projections
Dark matter remains one of the most intriguing mysteries of modern physics, and has sparked numerous experimental efforts to uncover its particle nature. Direct detection experiments using low threshold detectors in clean, ... -
Radon Background Reduction in DEAP-1 and DEAP-3600
(2011-01-10)The Dark Matter Experiment with Liquid Argon Using Pulse Shape Discrim- ination (DEAP) is a dark matter experiment based in the SNOLAB facility in Sudbury, Ontario. Its aim is to detect WIMPs, Weakly Interacting Massive ... -
Temperature Dependent Emission of Acrylic Relative to Tetrapheynl Butadiene (TPB)
After decades of astronomical observation and study, the majority of mass in the universe is known to be composed of dark matter, an unknown substance which is strictly non-luminous unlike the more familiar baryonic matter. ...
