Title: SPLENDOR: Searching for Light Dark Matter with Narrow-Gap Semiconductors
Abstract: SPLENDOR is a cross-disciplinary collaboration developing novel semiconductor detectors to search for low-mass, particle-like dark matter. Our approach combines low-bandgap semiconductor targets with ultra-low-noise cryogenic charge amplifiers to probe energy depositions below 1 eV. We have developed a modular detector platform optimized for rapid integration of new materials, featuring a two-stage cryogenic HEMT-based amplifier with a demonstrated charge resolution of 19 ± 4 electrons. This talk will review the motivation for sub-GeV dark matter detection with low-temperature semiconductors, describe SPLENDOR’s experimental design and calibration efforts, and discuss future directions in device development and charge amplification.

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.
