Abstract
SoLAr is a proposed liquid argon time projection chamber experiment that will be able to measure the “hep branch” of solar neutrinos. The scintillation light and the deposited charge signals are collected on the same readout plane that contains a combined grid of silicon photon multipliers and charge collection pixels. The combined light and charge readout allows for millimeter-scale resolution and light and charge matching. First prototypes were successfully operated in Bern, CH in cosmic-rays. The conceptual design of SoLAr, the advantages, and the first results of the SoLAr prototypes will be discussed in details in this proceeding.
