Three-dimensional Imaging for Large LArTPCs

Understand

High-performance event reconstruction is critical for current and future massive liquid argon time projection chambers (LArTPCs) to realize their full scientific potential.

• LArTPCs with readout using wire planes provide a limited number of 2D projections.
• In general, without a pixel-type readout it is challenging to achieve unambiguous 3D event reconstruction.
• As a remedy, we present a novel 3D imaging method, Wire-Cell, which incorporates the charge and sparsity information in addition to the time and geometry through simple and robust mathematics.
