Michael Wiescher, Freimann Professor of Physics published the biography “Arthur E. Haas – The Hidden Pioneer of Quantum Mechanics” at Springer. A German version is being published by the LIT Verlag in Vienna. Arthur E. Haas came to ND as a professor of physics in 1936 on the recommendation of Albert Einstein. At the time, he was a well known theoretical physicist who escaped from the growing dangers of fascism in Austria/Germany to the United States to build a new life.

NSF MRI awarded to Bardayan to conduct research on nuclear astrophysics

Author: Shelly Goethals

Professor Dan Bardayan received a Major Research Instrumentation (MRI) grant from the National Science Foundation to conduct research on nuclear astrophysics at the University of Notre Dame’s Nuclear Science Laboratory.

With the $505,000 grant to be matched with $217,000 from the University, Bardayan will develop a nuclear decay spectrometer called SABRE, the Silicon Array for Branching Ratio Experiments. SABRE will take advantage of the unique TriSol facility at the Nuclear Science Lab to measure proton and alpha branching ratios as small as one part in one-hundred thousand, which is characteristic of many important resonances of astrophysical interest.

Prof. Anna Simon will lead a project to develop a neutron irradiation station (NIS) at the Nuclear Science Laboratory at the University of Notre Dame. NIS will utilize a high-intensity proton beam from the 5U accelerator to produce a flux of neutrons at energies up to a few MeV via nuclear reactions on low-Z targets. First of its kind in the U.S., NIS will deliver monoenergetic neutron beams with intensities of the order of 108

deBoer offers new analysis of nuclear reaction data finds holes in a theory about the first stars

Uncertainty over First Stars

Stars are dutiful recyclers. The material used and discarded by one generation of stars is taken up and reused by the next. But that cycling process has trouble explaining the surprisingly high calcium concentrations in stars that formed early on. Astrophysicists have proposed that these old stars were seeded by a first generation that expired in “faint supernovae,” producing calcium but few other heavy elements. However, a new analysis of nuclear reaction measurements suggests that this model may not be so solid [1

Over the last few years CASPAR has driven forward with its for researching experimental plan. Work has continued through a global pandemic and underground blasting of nearby cavities. Students and faculty have pressed hard to complete crucial experiments before having to pause for extensive nearby excavations. Currently CASPAR has now been mothballed, but still has much to do.

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

Reducing nuclear reaction background uncertainties in large mass neutrino detectors

Author: Janet Weikel

Deboer 13can News

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.
