Pixelation: Bringing liquid noble element detectors into focus

The Department of Physics welcomes Dr. Jonathan Asaadi to present their weekly colloquia. Dr. Asaadi is currently an assistant professor in the physics department at the University of Texas Arlington. Before this, he was a postdoctoral researcher with Syracuse University from 2012 – 2015 working with professor. Mitch Soderberg.  He received his Ph.D. in 2012 from Texas A&M University under professor David Toback. He graduated from the University of Iowa in 2004 with a B.S in physics. His current research interests focus on understanding the most abundant massive particle in the universe, the neutrino.

Abstract: Future long baseline neutrino experiments such as the Deep Underground Neutrino Experiment (DUNE) call for the deployment of multiple multi-kiloton scale liquid argon time projection chambers (LArTPCs). To date, two detector readout technologies are being studied in large-scale prototype detectors: the single phase (SP) and dual phase (DP) detectors using projective charge readout wire based anode planes. These projective readout technologies come with a set of challenges in the construction of the anode planes, the continuous readout of the system required to accomplish the physics goals of proton decay searches and supernova neutrino sensitivity, and the 2D projective reconstruction of complex neutrino topologies.

This talk will go over the unorthodox solutions in both charge and light readout currently being pursued to overcome the challenges of projective readout and bring forward a true 3d pixel based readout for LArPTC’s.
