In January 2021, researchers at Sanford Underground Research Facility (Sanford Lab) returned a detector to the University of Notre Dame. The detector, which has been collecting data for most of 2020, is officially named the High EffiCiency TOtal absoRption spectrometer (HECTOR). During its residency at Sanford Lab in 2020, the HECTOR Detector helped researchers better understand how stars form elements. Click HERE…
Dr. James deBoer (UND) and Dr. Michael Febbraro (ORNL) have recently lead a research initiative to make new measurements of the 13C(a,n)16O reaction at energies relevant for background simulations for large volume neutrino experiments. These new measurements were made possible by pairing the Notre Dame Nuclear Science Laboratory’s new high current Sta. ANA accelerator with state-of-the-art deuterated liquid scintillation detectors recently developed at Oak Ridge National Laboratory.
Last week a team from Notre Dame, Dan Robertson and Orlando Gomez, were at the Sanford Underground Research Facility working 4850 feet underground to install HECTOR, Notre Dame’s high-efficiency, gamma-ray summing detector. The combined setup, called CASTOR, is now ready and soon be measuring alpha-capture reactions relevant for a wide and varied range of stellar burning scenarios.

Synopsis: Gold Nucleus is Wobbly
A rare kind of nuclear spinning motion has been detected in an isotope of gold.
Planets, footballs, and even some large molecules have something in common: they rotate as rigid, classical bodies. Atomic nuclei are another matter, in that quantum mechanics allows strange new modes of motion. In experiments involving a short-lived isotope of gold, 187…
Adam Clark has been awarded as the first recipient of the NSL’s Applied Nuclear Fellowship (funded by the Nuclear Regulatory Commission). This fellowship was created in 2019 for the purpose of training students in applied nuclear physics and is awarded to senior graduate students who exhibit a clear interest in applied research with broad applications.
Nuclear Physics Professors Ani Aprahamian, Manoel Couder, James deBoer, Daniel Robertson and Anna Simon as well as research associate Dr. Xilu Wang and a fifth year graduate student Erika Holmbeck presented their research at the 9th Nuclear Physics in Astrophysics conference that took place from September 15th to 20th in Budenheim, Germany.
Professor Maxime Brodeur, Janet Weikel from the Nuclear Science Laboratory of the University of Notre Dame, and Professor Thomas Brunner from McGill University co-organized the 13th International Conference on the Stopping and Manipulation of Ions (SMI-2019)…
A team of faculty from the Nuclear Science Laboratory, Daniel Robertson, Manoel Couder, Anna Simon and Joachim Goerres, led by Michael Wiescher received 4-year support from the NSF to continue measurements at the underground accelerator facility investigating reactions important for the stellar nucleosynthesis processes.
Patricia Huestis has won an award from the DOE Office of Science Graduate Student Research (SCGSR) Program. This supplemental award is given to outstanding U.S. graduate students to pursue part of their graduate thesis research at a DOE laboratory. Patricia will spend the summer of 2019 working at the Pacific Northwest National Laboratory under the guidance of Drs. Sue Clark and Greg Kimmel.
JINA-CEE has continued a successful initiative to help Boy Scouts earn their Nuclear Science Merit badges at ISNAP. 18 scouts attended a workshop on January 20th with their parents. Graduate student Bryce Frentz served as Merit Badge Counselor and was joined by two Notre Dame physics majors in leading the activities
The University of Michigan's Applied Nuclear Science Group, led by Professor Igor Jovanovic, visited the University of Notre Dame last week to perform a series of experiments using the FN Tandem accelerator. The experiments centered around the acceleration of deuterons into a boron-11 target, which produces unique high-energy neutrons and gamma-rays. This reaction was in turn used as a mixed-particle interrogation source in conjunction with a variety of detection systems, including organic, inorganic, and semi-conductor detectors.
Ani Aprahamian, the Frank M. Freimann Professor of Physics, and Yuri Oganessian, chairman of the international scientistic board of the Alikhanian National Science Laboratory met with the President of Armenia Serzh Sargsyan on November 6. Aprahamian and Oganessian were invited to attend the World Conference in Yerevan. The Armenian President was highly appreciative of their continued contribution to physics and mathematics progression as well as educating the next generation of future scientists.

As part of continued support for the JINA R-matrix code AZURE2, a workshop was held at the Institute of Modern Physics (Chinese Academy of Sciences) in Lanzhou, China from September 18th to 22nd. Dr. James deBoer presented lectures and tutorials that emphasized the practical use of the code.
The goal of this Major Research Instrumentation (MRI) grant was to modify the low energy injection system of the FN tandem electrostatic accelerator of the Nuclear Science Laboratory (NSL) at the University of Notre Dame (ND) to provide higher mass resolution necessary for improved isotopic selectivity at isotopic masses beyond sulfur and chlorine.
CASPAR researchers Daniel Robertson and Michael Wiescher have been featured in the Autumn 2017 issue of the Notre Dame Magazine written by Dr. Kenneth Garcia '08 about his personal experience of going underground in the Homestake Mine of South Dakota where CASPAR is located. The online version of the article can be found here…
The NSL faculty retreat for 2017 took place at Fernwood Botanical Garden in Niles, MI on August 26. The group discussed current issues and strategic short-term and long-range plans on scientific focuses and resources for the Nuclear Science Laboratory.…
The Ph. D. thesis of Dr. James Matta, titled "Exotic Nuclear Excitations: The Transverse Wobbling Mode in 135Pr" has been published as a book by the well-known science publisher Springer under the "Springer Theses" series.
The Compact Accelerator System for Performing Astrophysical Research (CASPAR) is featured in the science section of WIRED magazine.
The National Nuclear Security Administration's Office of International Nuclear Safeguards presented this year's Joule Award "in recognition of outstanding contributions made for transferring: 19F(α,n) Na Cross Section for Uranium Enrichment to international partners." The Versatile Array of Neutron Detectors at Low Energy, also known as VANDLE, array of plastic scintillators, developed with Stewardship Science Academic Alliances funds, was critical to the success of this project.
The Compact Accelerator System for Performing Astrophysical Research (CASPAR) recently reached a huge milestone with the delivery of first beam to target. This marks a significant step in the creation and operation of the first U.S. deep underground accelerator laboratory.
Three graduate students (Adam Clark, Austin Nelson, and Craig Reingold) of ISNAP participated in this year’s Notre Dame Day live broadcast on April 23rd to gain votes for the Graduate Physics Society (GPS). During the broadcast, the students of the GPS performed a physics demo in which they used a sledgehammer to smash a cinder block on the chest of the broadcast host and Notre Dame alumni Vic Lombardi. This is a classic physics demonstration that illustrates the concepts pressure, inertia, and the conservation of energy.…
Professor Ann Simon's paper “Impact of the α optical model potential on the γ-process nucleosynthesis” investigates the impact of the nuclear properties on the γ-process nucleosynthesis. γ-process is a nucleosynthesis scenario responsible for production of proton-rich isotopes of heavy nuclei. Since the reaction network that describe the γ-process is based on model predictions of the rates of all the reactions involved (only in few cases these can be measured directly) understanding of the impact of the current models of the nuclear properties is important for constraining the predictions of the network calculations. In this work, the analysis focused on the α-optical model potential; future work will investigate impact of other parameters, e.g. γ-strength function.
