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.

Dan Dwyer (LBNL) – Demonstration of a true 3D micro-power sensor for liquid argon time projection chambers

April 27, 2018 @ 12:00 pm - 1:00 pm

Time projection chambers (TPCs) based on the ionization of cryogenic liquids are a prominent tool for neutrino oscillation, neutrinoless double beta decay, and dark matter experiments. Over the past two years I have pursued the development of a novel charge readout sensor providing true 3D imaging of particle interactions in large-scale liquid argon TPCs. The sensor must meet stringent requirements on noise (<600 electron), power (<100 microwatts per channel), and scalability (digital multiplexing of 100,000 channels per square meter), all at cryogenic temperatures. Such a scalable 3D micro-power sensor would enable operation of liquid argon TPCs in high-occupancy environments, such as the near detector site of the Deep Underground Neutrino Experiment (DUNE). I will present my recent mad dash to a successful demonstration of 3D micro-power imaging of particle tracks in liquid argon, and discuss what worked and what didn’t work along the way. I will also discuss the potential impact on upcoming neutrino measurements.
