Unravelling the Mysteries of Neutrinos

Dr. Stephen Parke Fermilab Neutrinos are the most numerous massive particles in the Universe. Their masses are very tiny, no larger than one millionth the mass of the electron. Are they like all the known massive fermions, being four component particles, or are they a new type of fermion never seen before, a two component fermion? Are there only only three neutrinos or are there more species of neutrinos? Of the three neutrinos we know of, we have determined part of the massing pattern but not the completely pattern.

50th Anniversary of UK's Particle Accelerator

Celebrating its 50th anniversary on UK’s campus, the Accelerator Lab is the giant cylinder in front of the Chem/Phys Building. Mysterious to many visitors to campus, and affectionately but incorrectly referred to as the “Atom Smasher” by others, it houses a 7-million-volt small particle accelerator used by the Physics Department for various experiments, such as studying the form and shapes of stable nuclei.

Marcus T. McEllistrem, the man that helped bring the accelerator to campus reflects back on some of its history.
