Description

Building on the success of operating Time Projection Chambers (TPCs) for directional neutron detection the D3 project is designing a Negative Ion TPC (NITPC) as a directional dark matter detector prototype with high definition (HD) pixel chip readout. In addition SF6 has recently been proposed as a possible replacement for the CF4/CS2 negative ion mixture and it has been observed that gain is achievable in a SF6 based detector. We seek to design a detector which allows for maximum drift length, uses Gas Electron Multipliers (GEMs) for amplification, and the ATLAS FE-I4b chip for ionization readout. Such a design would allow for 3-D tracking with powerful background suppression and could serve as “unit-cell” for a large, future, directional detector.
