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: Yashwanth Bezawada(UC Davis)Title: Pulsed neutron detection

May 10 @ 12:00 pm - 1:00 pm


Date: May 10, 2024

Time: 12:00 pm – 1:00 pm

Location: Sessler Conference Room – 50A-5132 [Hybrid and In-Person]

Speaker: Yashwanth Bezawada (UC Davis)

Title:  Quest to understand neutron propagation in liquid Argon

Abstract: Liquid Argon (LAr) has become the primary detector material in many neutrino and dark matter experiments like DUNE, SBND, ICARUS, MicroBooNE, and DarkSide. In particular, multi-kiloton experiments like the Deep Underground Neutrino Experiment (DUNE) have stringent requirements for systematic uncertainties on the energy scale and resolution. Neutron production from neutrino interaction brings a large uncertainty on neutrino energy reconstruction in the form of missing energy. One of the proposed calibration systems is the Pulsed Neutron Source (PNS) system, which utilizes neutrons traveling long distances in liquid argon to calibrate the enormous DUNE far detector volume.

Thus, it is of utmost importance to understand neutron propagation and capture in liquid argon. The group at Davis is involved in an effort to measure the total neutron cross-section on Argon for a wide range of neutron energies. In this talk, I will talk about the ARTIE experiment that made the first effort to measure the cross-section dip at 57 keV, the Multiple Argon Experiments (MArEX) initiative, which was established to perform accurate transmission and capture measurements at the n_TOF facility in CERN, and the neutron generator test performed at CERN to test the feasibility of the PNS calibration system.
