University of Maryland Radiation Facilities
Much of the KRG research is enabled by the unique set of tools that comprise the UMD Radiation Facilities. Tim Koeth is the past Director of the facility, and is now the Director of Research.
Uranium Club – 
Miriam Hiebert and Tim Koeth are under contract with CRP to write a book that chronicles the fascinating story of discovery and re-discovery of innocuous Uranium cubes that carry the responsibility of launching the Manhattan Project, the use of atomic weapons in wartime, the cold war, and the perpetual nuclear hostage situation our globe faces. These cubes also represent the inquiry into a technology that could ultimately save our planet. In 2019, Tim Koeth loaned his Heisenberg Cube to the National Museum of Nuclear Science and History for display in an exhibit created around the relic called the Dark Cube.
National Museum of Nuclear Science and History
Or NMNSH, is located in Albuquerque, New Mexico. Tim Koeth is on the Board of Trustees for the museum and is involved in educational outreach programs in the field of nuclear science and technology.
Many colleagues, contributing members, and friends of the KRG are amateur nuclear scientists, and we have done our best to document our professional-level educational activities. You raise an eyebrow to amateur and nuclear in the same sentence ? Yes, the word amateur comes from the Latin word amatore, which means love or lover, and the interpretation is that an amateur is motivated by the love of a subject rather than for the financial reward. Together, this group’s accomplishments are a story of cooperation and collaboration. “Alone we can do so little, together we can do so much.”– Helen Keller
Tim Koeth began his career as an educator with his amateur home-built cyclotron, that for the past 27 years has been a non-stop source of education in accelerator science and engineering for over 100 undergraduate students, many high school students, and several students of life.
Almost all members of the Koeth group have been either students or instructors (or both) for the US DOE’s USPAS (United States Particle Accelerator School). This is a national resource with unique educational tools of which all accelerator people (undergrads, graduate students, laboratory personnel, clinicians, etc.) should be aware and utilize. In 2015, Tim’s Cyclotron (then at Rutgers) was the centerpiece of the USPAS summer session 2-week class on cyclotrons.
Partnered with USPAS and the University of Maryland Department of Materials Science and Engineering, the Koeth Group produced a set of nine in-depth educational videos centered around the 12-inch Cyclotron. Each episode focuses on a different piece of the Cyclotron, showcasing the fundamental particle accelerator physics while guiding the viewer through the principle operation and various high-energy experiments. The first set of videos can be found on YouTube and on the USPAS homepage. We are currently working on another set of videos focused on Neutron production and Nuclear experiments using the 12-inch Cyclotron.
