Dark Matter directional detection: comparison of the track direction determination

Understand

Several directional techniques have been proposed for a directional detection of Dark matter, among others anisotropic crystal detectors, nuclear emulsion plates, and low-pressure gaseous TPCs.

• The key point is to get access to the initial direction of the nucleus recoiling due to the elastic scattering by a WIMP.
• In this article, we aim at estimating, for each method, how the information of the recoil track initial direction is preserved in different detector materials.
• We use the SRIM simulation code to emulate the motion of the first recoiling nucleus in each material.
