Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

Speaker: Gabriela Rodrigues Araujo (University of Zurich)- Title: Light-sheet microscopy of color centers: A new venue for neutrino and dark matter detection with passive crystals

April 10, 2023 @ 4:00 pm - 5:00 pm


This is an In-Person [HYBRID] Event

LOCATION: Sessler Conference Room – 50A – 5132

DATE: April 10, 2023

TIME: 4:00  pm

TITLE: Light-sheet microscopy of color centers: A new venue for neutrino and dark matter detection with passive crystals

ABSTRACT: Most of the techniques currently used to detect nuclear recoils from dark matter and neutrinos rely on the collection of charge, prompt scintillation photons or phonons. In this talk, I will discuss a new approach: The use of light-sheet fluorescence microscopy to detect a specific type of crystal defect, so called color centers (CCs), which could be induced by nuclear recoils in solid-state materials. Since CCs require little energy to form (10-50 eV), the proposed detectors can search for particle interactions at unexplored low-energy regions. Despite the nm-size of these defects, excited CCs re-emit color in the visible range, a feature that facilitates their detection. To make this detection channel competitive for rare-event search, a fast imaging method of single CCs is necessary. The PALEOCCENE collaboration works towards this goal: a scalable read-out of CCs for passive detectors of neutrinos and dark matter. In the talk I will discuss the concept, the current R&D and possible applications for dark matter, CEvNS, and nuclear-nonproliferation safeguards.
