Abstract:

This paper presents a measurement of the ratio of photon to electron production and the scintillation spectrum in a popular gas for time projection chambers, carbon tetrafluoride (CF4), over the range of 200-800 nm; the ratio is measured to be 0.34 ± 0.04. This result is of particular importance for a new generation of dark matter time projection chambers with directional sensitivity which use CF4 as a fill gas. © 2008 Elsevier B.V.

Observation of the "head-tail" effect in nuclear recoils of low-energy neutrons

Journal of Physics Conference Series 110:6 (2008)

Abstract:

We present an experimental method to determine the direction tag ("head-tail") of dark matter wind using a low-pressure time-projection chamber. We demonstrate the method by tagging the direction of the elastic nuclear recoils created in the scattering of low-energy neutrons with CF4 nuclei. The decreasing ionization rate along the recoil trajectory allows us to determine the direction of the incoming neutrons, and proves that the "head-tail" effect can be measured.
