Measurement of directional range components of nuclear recoil tracks in a fiducialised dark matter detector
J. B. R. Battat, E. J. Daw, A. C. Ezeribe +16
We present results from the first measurement of axial range components of fiducialized neutron induced nuclear recoil tracks using the DRIFT directional dark matter detector. Nucl…
Imaging Fe Electron Tracks in a GEM-based TPC Using a CCD Readout
N. S. Phan, E. R. Lee, D. Loomba
Images of resolved 5.9 keV electron tracks produced from Fe X-ray interactions are presented for the first time using an optical readout time projection chamber (TPC). The c…
Low Threshold Results and Limits from the DRIFT Directional Dark Matter Detector
J. B. R. Battat, A. C. Ezeribe, J. -L. Gauvreau +18
We present results from a 54.7 live-day shielded run of the DRIFT-IId detector, the world's most sensitive, directional, dark matter detector. Several improvements were made relati…
Readout technologies for directional WIMP Dark Matter detection
J. B. R. Battat, I. G. Irastorza, A. Aleksandrov +90
The measurement of the direction of WIMP-induced nuclear recoils is a compelling but technologically challenging strategy to provide an unambiguous signature of the detection of Ga…
The novel properties of SF for directional dark matter experiments
N. S. Phan, R. Lafler, R. J. Lauer +4
SF is an inert and electronegative gas that has a long history of use in high voltage insulation and numerous other industrial applications. Although SF is used as a tr…
First measurement of nuclear recoil head-tail sense in a fiducialised WIMP dark matter detector
J. B. R. Battat, E. Daw, A. C. Ezeribe +17
Recent computational results suggest that directional dark matter detectors have potential to probe for WIMP dark matter particles below the neutrino floor. The DRIFT-IId detector…
GEM-based TPC with CCD Imaging for Directional Dark Matter Detection
N. S. Phan, R. J. Lauer, E. R. Lee +3
The world's leading directional dark matter experiments currently all utilize low-pressure gas Time Projection Chamber (TPC) technologies. We discuss some of the challenges for thi…
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…
First background-free limit from a directional dark matter experiment: results from a fully fiducialised DRIFT detector
J. B. R. Battat, J. Brack, E. Daw +28
The addition of O2 to gas mixtures in time projection chambers containing CS2 has recently been shown to produce multiple negative ions that travel at slightly different velocities…
Radon in the DRIFT-II directional dark matter TPC: emanation, detection and mitigation
J. B. R. Battat, J. Brack, E. Daw +26
Radon gas emanating from materials is of interest in environmental science and also a major concern in rare event non-accelerator particle physics experiments such as dark matter a…
Long-term study of backgrounds in the DRIFT-II directional dark matter experiment
