Description
Liquid argon time-projection chambers are the primary neutrino detector technology for DUNE. However due to the O(100us) readout time of large LArTPCs, a LArTPC at the DUNE near detector will encounter substantial neutrino interaction pile-up. To overcome pile-up, we have developed a novel 3D pixelated LArTPC based around a custom cryogenic-compatible ASIC called LArPix. The LArPix-v1 ASIC demonstrated the key requirements of the LArPix concept, namely, low power and low noise amplification, digitization, and self-triggered readout at cryogenic temperatures. The upcoming LArPix-v2 chip aims to demonstrate robust, scalable performance in a ton-scale TPC. I will present on the R&D effort targeting a successful LArPix-v2 design and implementation.
