Title: The Gamma-Ray Energy Tracking Array – GRETA
Abstract: The Gamma-Ray Energy Tracking Array (GRETA) Project started in 2017, following nearly a decade of successful science with the predecessor GRETINA array. Led by the Nuclear Science Division at LBNL, and with a team including scientists, engineers, and technical staff from NSD, Engineering, and ESnet, as well as from partner institutions ANL, ORNL, and FRIB, GRETA recently completed the CD-E-4A milestone. It is currently being installed at the Facility for Rare Isotope Beams (FRIB), with first science measurements expected at the end of 2026. I will review the GRETA project goals, both scientific and technical, and how it progressed from concept to fabrication to anticipated first science at FRIB.

Date: January 16, 2026
Time: 12:00 pm – 1:00 pm

Speaker: Ralf Konietzka (Harvard)
Title: Fast Radio Burst Cosmology in IllustrisTNG: Forward Modeling Dispersion Measures to Constrain Baryonic Feedback
Abstract: The dispersion measures (DMs) of Fast Radio Bursts (FRBs) arise predominantly from free electrons in the large-scale structure of the Universe. The increasing number of FRB observations have started to empirically constrain the distribution of cosmic baryons, making it crucial to accurately forward model their propagation within cosmological simulations.
In this talk, I present a method for measuring FRB DMs in IllustrisTNG that continuously traces rays through the simulation while reconstructing all traversed line segments within the underlying Voronoi mesh. Leveraging this technique, we create over 20 publicly available DM catalogs, including a full-sky DM map observed from a Milky Way-like environment.
Our method addresses a problem in previous TNG-based studies, in which a sparse snapshot sampling in the path integral leads to a misestimation of the standard deviation and higher moments of the DM distribution p(DM|z) by over 50%.
Confronting our simulated FRB catalogs with recent observations from DSA-110, ASKAP, and CHIME, I quantify the distribution of baryons relative to the underlying matter, allowing us to place new constraints on the strength of baryonic feedback.

Title: Scintillation photon counting detector concept for advancing time-of-flight PET
Abstract: Positron emission tomography (PET) is a powerful imaging modality for providing in vivo molecular function in nuclear medicine. The precise timing capability of positron annihilation photon interaction within the scintillation detectors has remarkably revolutionized the diagnostic performance of PET, motivating the radiation instrumentation researchers to pursue sub-100-ps time resolution at the system level. The biomedical imaging team at LBL ANP is currently developing a novel time-of-flight PET detector concept that extracts unique timestamps of the early scintillation photons for event timing and positioning. This approach integrates a large-volume scintillation crystal, silicon photomultipliers, and low-noise high-frequency readout electronics. Our recent progress in design optimization and prototype characterization will be presented.

Title: Hidden track structures in liquid xenon and their implications for dark matter searches
Abstract: Dual-phase liquid xenon detectors are entering a regime where new insights into signal formation are required to make robust discoveries of WIMPs and solar neutrino CEvNS. I will present two results from the LUX-ZEPLIN (LZ) experiment showing that key signals and backgrounds are not described by standard models of light and charge production in liquid xenon. First, double-electron-capture backgrounds in WIMP searches produce unexpectedly strong electron-ion recombination, generating events that mimic nuclear recoils. Second, neutron calibrations reveal excess fluctuations in nuclear recoil signals, boosting the observable rates of low-mass dark matter and solar neutrino CEvNS. I will describe how the underlying physics of track structures impacts current dark matter searches and the predictions of future experiments.
