Searches for dark matter–induced recoils have made impressive advances in the last few
years. Yet the field is confronted by several outstanding problems. First, the inevitable …

Cosmological observations indicate that most of the matter in the Universe is Dark Matter.
Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs) can be detected …

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 …

The addition of O 2 to gas mixtures in time projection chambers containing CS 2 has recently
been shown to produce multiple negative ions that travel at slightly different velocities. This …

The search for a novel technology able to detect and reconstruct nuclear and electron recoil
events with the energy of a few keV has become more and more important now that large …

Recoil imaging entails the detection of spatially resolved ionization tracks generated by
particle interactions. This is a highly sought-after capability in many classes of detector, with …

SF 6 is an inert and electronegative gas that has a long history of use in high voltage
insulation and numerous other industrial applications. Although SF 6 is used as a trace …

The nature of dark matter is still unknown and an experimental program to look for dark
matter particles in our Galaxy should extend its sensitivity to light particles in the GeV mass …

The most mature directional dark matter experiments at present all utilize low-pressure gas
Time Projection Chamber (TPC) technologies. We discuss some of the challenges for this …

Abstract The Time Projection Chamber (TPC) is an ideal candidate to finely study the
charged particle ionization in a gaseous medium. Large volume TPCs can be readout with a …
