Description
Liquid Argon Time Projection Chamber (LArTPC) is a premier technology in neutrino detector designs. The field response model describes the electric currents induced in the anode plane when ionization electrons drift in the chamber. Field response is critical for TPC readout simulation and charge reconstruction. A novel pixelated charge readout technology, LArPix, has been developed for LArTPCs. We present a new 3D field response simulation for these pixelated anode designs used in the Module-0 Demonstrator, which is operated as a prototype for the DUNE liquid argon near detector. In the prototype detector run, evidence of the readout triggered by drifting charge in advance of the charge arrival at the anode plane has been noticed. Thus, this field response simulation is also crucial in understanding electronics response and optimizing pixel pad geometry to reduce the induced signal trigger effect.
