About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

SPECIAL INPA SEMINAR

Date:  Thursday, February 1, 2024

Time: 12:00 PM – 1:00 PM

Location: INPA Conference Room–5026 [Hybrid and In-Person]

Speaker: Mark Anderson (Queen’s University)

Title: Advancing nuclear and particle physics with deep learning: from event reconstruction to signal denoising

Abstract: In this talk, I will present my research on advancing nuclear and particle physics using deep learning. The first portion of the presentation will focus on the SNO+ experiment, a multi-purpose neutrino experiment with the primary goal of searching for neutrinoless double-beta decay. In particular, my work involves developing deep learning-based techniques for event reconstruction of particle interactions in the detector. Currently, SNO+ uses a chain of algorithms involving maximum likelihood estimation. I will demonstrate that my independent, deep learning approach can be used to improve the reconstruction accuracy, while also offering substantial gains in speed. This has implications on volume fiducialization and background rejection.
In the second part of my talk, I will present studies on a deep convolutional autoencoder designed to remove electronic noise from a p-type point contact high purity germanium detector. With their intrinsic purity and excellent energy resolutions, these detectors are suitable for a variety of rare event searches such as neutrinoless double-beta decay, dark matter candidates, and other exotic physics. However, noise from the readout electronics can make identifying events of interest more challenging. I will highlight several studies that show that detector performance can be improved when signals are denoised with the autoencoder, leading to better physics outcomes.
While both of these projects are applied to data from specific detector technologies, the methods I have developed are broadly applicable. The groups I work with have begun exploring new applications of my research with promising results. At the end of the talk, I will discuss some specific extensions and provide an outlook for the future.

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
