Tim Koeth

Koeth, Timothy

Associate Research Professor
Director, UMD Nuclear Reactor and Radiation Facilities
1202J Energy Research Facility

Research Interests: 

Professor Koeth joined the University of Maryland faculty in 2009. He is leading research in nonlinear charged particle beam optics and is currently Director of the University of Maryland Nuclear Reactor and Radiation Facilities.

His current research activities include intense electron and ion beam accelerators and associated beam optics.  He is presently PI on a nonlinear beam optics experiment being performed on the University of Maryland Electron Ring (UMER).  His research also includes cyclotrons, cathodes, pulsed power, high power RF, normal and superconducting RF structures, as well as the radiological sciences.

The UMD Radiation Facilities includes the Maryland 250 kW Training Reactor (MUTR), a Panoramic Irradiator, and two high power electron linear accelerators.  Professor Koeth is an NRC licensed senior reactor operator.  He is interested in coupling his experience of cyclotrons and intense charged particle beams with subcritical piles in the field of accelerator driven systems and in the medical uses of accelerators.

He has more than seventy-five scientific publications, has given twenty invited presentations of his work, holds one patent, and is involved in collaborations throughout the world.

Current Research Projects: 

PI:  Nonlinear Charged Particle Beam Optics
Co-PI:  Accelerator Research Studies


Professor Koeth is active in accelerator physics education; he has advised six graduate students and more than twenty undergraduate students.  His educational undergraduate accelerator program has brought seven undergraduate physics students to pursue accelerator physics careers in both industry and academia.  In the Fall of 2014 he will begin offering an educational cyclotron course at the University of Maryland.

He is currently teaching Reactor and Radiation Measurements Laboratory, ENMA432, SPR2015.

He is an instructor at the United States Particle Accelerator School (USPAS) and has developed a new course on cyclotron design, which was taught at Duke University in January 2013 and will be offered during the summer 2015 USPAS session.  In recognition of his undergraduate educational efforts, he was invited to serve on the scientific program committee for the 20th International Conference on Cyclotrons and Their Applications (Cyclotrons 2013) and to chair the inaugural session on educational cyclotrons.

Professor Koeth holds a visiting faculty appointment at Rutgers University.


Professor Koeth received a B.S. in physics and a Ph.D. in physics from Rutgers University in 1997 and 2009, respectively.  He completed his doctoral work at Fermi National Accelerator Laboratory (Fermilab), where he led two accelerator projects under the supervision of Dr. Helen Edwards.  Koeth led the effort to bring the first high-gradient superconducting RF cavity at Fermilab into operation.  Next he designed and performed the first experimental demonstration of a longitudinal-transverse phase space exchange.  His thesis won the Rutgers’ Professor Plano Thesis Award acknowledging his thesis as the overall best that year.
