Welcome to the Center for Exploration of Energy and Matter at Indiana University.
IUCF Injector Magnet Project
We are planning to display a sector of the IUCF injector magnet outside the Multidisciplinary Engineering and Sciences Hall (former cyclotron building). The magnet is part of the original test injector constructed for the IU cyclotrons, which operated from 1976-2014. We are raising funds for the installation and maintenance of the magnet sector as a permanent tribute to the legacy of the IU Cyclotron Facility [Read more about the IUCF Injector Magnet Project]
January 26, 2021 -- The COHERENT experiment running at Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. This work, recently published in Physical Review Letters was led by IU physicists Dan Salvat and Rex Tayloe and was the Ph.D. work of Jacob Zettlemoyer. The experiment employed a cryogenic liquid argon device to see the faint signature of a recoil argon nucleus in response to coherent elastic neutrino-nucleus scattering -- called ''CEvNS''. This first detection of CEvNS from an argon nucleus backs up a 2017 observation on cesium-iodide by COHERENT and opens the door for future, higher-precision measurements of CEvNS for increased understanding of supernovae, nuclear structure, and dark matter.
January 1, 2021 -- CEEM graduate student Douglas Wong (advisor Dr. Chen-Yu Liu) has been awarded a 2021 DOE Office of Science Graduate Student Research (SCGSR) award. This award will support his dissertation research on the measurement of the neutron electric dipole moment. Doug will be putting together the magnetically shielded room and commission the neutron apparatus at Los Alamos National Laboratory.

September 5, 2020 -- Dr. Chen-Yu Liu featured in DOE article "The Mystery of the Neutron Lifetime"for her group's recent work on "Using a magneto-gravitational trap to measure neutrons with unprecedented precision."
June 15, 2020 -- Recent work by Prof. Mike Snow and collaboration group on search for exotic spin-dependent couplings of the neutron published in Physical Review D [Read more about exotic spin-dependent couplings of neutrons]
April 8, 2020 -- First physics results from the upgraded Belle II experiment, the search for a new Z' vector boson "portal" into dark matter, published (Editor's feature/suggested) in Physical Review Letters [Read more about the Belle II experiment]
December 9, 2019 -- The COHERENT experiment has recently published the first constraint of the coherent elastic neutrino-nucleus scattering process in argon as as an Editor's Suggestion in Physical Review D. This measurement was led by the IU CEEM neutrino group and was the thesis work of Matthew Heath (Ph.D.2019). This experiment continues to run at the ORNL Spallation Neutron Source and new results from a more sensitive run are coming soon.
