[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] educators (UEs) have a long history teaching physics not only in formal classroom settings but also informal outreach environments. The pedagogical practices UEs been widely studied, they may provide insight into preparation. We investigate interactions between children an afterschool program facilitated by university students from Colorado Boulder. In this program, undergraduates,...
We report the demonstration of a low-power pixelated readout system designed for three-dimensional ionization charge detection and digital liquid argon time projection chambers (LArTPCs). Unambiguous 3D was achieved using custom-designed system-on-a-chip ASIC (LArPix) to uniquely instrument each pad in array charge-collection pads. The LArPix ASIC, manufactured 180 nm bulk CMOS, provides 32 channels charge-sensitive amplification with self-triggered digitization multiplexed at temperatures...
We develop a novel Time Projection Chamber (TPC) concept suitable for deployment in kilotonne-scale detectors, with charge-readout system free from reconstruction ambiguities, and robust TPC design that reduces high-voltage risks while increasing the coverage of light-collection maximizing active volume. This could be used as far detector module Deep Underground Neutrino Experiment (DUNE). For system, we charge-collection pixels associated application-specific integrated circuits currently...
For the field of high energy physics to continue have a bright future, priority within must be given investments in development both evolutionary and transformational detector that is coordinated across national laboratories with university community, international partners other disciplines. While fundamental science questions addressed by never been more compelling, there acute awareness challenging budgetary technical constraints when scaling current technologies. Furthermore, many...
The Instrumentation and Measurement course unit at the University of Western Sydney is taken by third year engineering students. integrates knowledge gained to date with an emphasis on practical completions. While delivery via combined lecture/tutorials practicals, it in practicals that a difference found. Students are required sequentially complete set tasks over 13 teaching weeks point demonstrating correct operation lab supervisor. generally work individually, each session having one or...
We develop a novel approach for Time Projection Chamber (TPC) concept suitable deployment in kilotonne scale detectors, with charge-readout system free from reconstruction ambiguities, and robust TPC design that reduces high-voltage risks while increasing the coverage of light collection system. This could be deployed as Far Detector module Deep Underground Neutrino Experiment (DUNE) neutrino-oscillation experiment. For system, we use charge-collection pixels associated application-specific...
A 32-channel ASIC called LArPix, intended for instrumenting pixelated readout of Liquid Argon Time Projection Chambers (LAr-TPCs), is presented. The reduced capacitance and relaxed noise specifications a LAr-TPC allow significant power reductions relative to traditional wire plane-based LAr-TPC. Each channel employs largely dynamic signal processing that consumes low when idle. To reduce the number cryostat penetrations manageable level, multiple LArPix chips can be daisy chained...
