Transport properties of electrons in CF4
T. Caldwell, A. Roccaro, T. Sahin +17
Carbon-tetrafluoride (CF4) is used as a counting gas in particle detectors, but some of its properties that are of interest for large time-projection chambers are not well known. W…
DMTPC-10L: Direction-Sensitive Dark Matter Detector Prototype
D. Dujmic, P. Fisher, R. Lanza +13
The known direction of motion of dark matter particles relative to the Earth may be a key for their unambiguous identification even in the presence of backgrounds. We describe a pr…
A Measurement of Photon Production in Electron Avalanches in CF4
A. Kaboth, J. Monroe, S. Ahlen +13
This paper presents a measurement of the ratio of photon to electron production and the scintillation spectrum in a popular gas for time pro jection chambers, carbon tetrafluoride…
Observation of the 'head-tail' effect in nuclear recoils of low-energy neutrons
D. Dujmic, H. Tomita, M. Lewandowska +13
Directional detection of dark matter can provide unambiguous observation of dark matter interactions even in the presence of background. This article presents an experimental metho…
