Low-Energy Electron-Track Imaging for a Liquid Argon Time-Projection-Chamber Telescope Concept using Probabilistic Deep Learning by M. Buuck et al. on Monday 21 November The GammaTPC is an MeV-scale single-phase liquid argon time-projection-chamber gamma-ray telescope concept with a novel dual-scale pixel-based charge-readout system. It promises to enable a significant improvement in sensitivity to MeV-scale gamma-rays over previous telescopes. The novel pixel-based charge readout allows for imaging of the tracks of electrons scattered by Compton interactions of incident gamma-rays. The two primary contributors to the accuracy of a Compton telescope in reconstructing an incident gamma-ray's original direction are its energy and position resolution. In this work, we focus on using deep learning to optimize the reconstruction of the initial position and direction of electrons scattered in Compton interactions, including using probabilistic models to estimate predictive uncertainty. We show that the deep learning models are able to predict locations of Compton scatters of MeV-scale gamma-rays from simulated pixel-based data to better than 0.6 mm RMS error, and are sensitive to the initial direction of the scattered electron. We compare and contrast different deep learning uncertainty estimation algorithms for reconstruction applications. Additionally, we show that event-by-event estimates of the uncertainty of the locations of the Compton scatters can be used to select those events that were reconstructed most accurately, leading to improvement in locating the origin of gamma-ray sources on the sky. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2207.07805v2

Schon seit vielen Jahrzehnten träumen Wissenschaftlerinnen und Wissenschaftler von einem funktionsfähigen Quantencomputer. Parallel dazu wird an Quantenalgorithmen geforscht, das ist gewissermaßen die Software von Quantencomputern. Wie man solche Algorithmen entwickelt und welche Herausforderungen es dabei gibt, berichtet Barbara Kraus von der Technischen Universität München in dieser Folge des Podcasts. *** Ein Beitrag von Kim Hermann, gesprochen von Elias Emken.

Rund siebzig Prozent der Erdoberfläche sind mit Wasser bedeckt. doch wir wissen kaum etwas über unsere Ozeane. Viele Fragen, vor allem zum Klimawandel, kreisen um die Rolle und Bedeutung der Ozeane. Die Forschung sucht unermüdlich nach Antworten. Unerschrockene und leidenschaftliche Wissenschaftler*innen entdecken unter Wasser unbekannte Welten. Die Journalistin Susanne Brahms holt sie vor das Mikrofon um ihnen die Geheimnisse ihrer Forschung zu entlocken.
