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.

November 13 @ 12:00 pm - 1:00 pm

Speaker: Tomi Akindele (Lawrence Livermore National Laboratory)

 Title: Antineutrinos as a Nuclear Safeguards Tool


To date, antineutrino experiments built for the purpose of demonstrating a nonproliferation capability have typically employed organic scintillator, and been situated as close to the core as possible – typically a few meters to tens of meters distant, and have not exceeded a few tons in size.

One problem with this approach is that proximity to the reactor core  requires accommodation by the host facility. Water Cherenkov detectors located offsite, at distances of a few kilometers or greater, may facilitate non-intrusive monitoring and verification of reactor activities over a large area. 

As the standoff distance increases, the detector target mass must scale accordingly.  This talk quantifies the degree to which a kiloton-scale gadolinium-doped water Cherenkov  detector can exclude the existence of undeclared reactors within a specified radial distance, and remotely detect the presence of a hidden reactor in the presence of declared reactors, by verifying the operational power and standoff distance. 

A Feldman-Cousins based likelihood analysis was used to quantify the detector’s  ability to exclude the existence of undeclared reactors. A 1-kton scale Water Cherenkov detector can exclude gigawatt-scale nuclear reactors up to tens of kilometers. When attempting to identify the specific location of a reactor, the detector response and analysis cannot delineate between the reactor power and baseline.

November 13
12:00 pm - 1:00 pm

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.

INPA Common Room (50-5026)
