Ralph Fiorito

Fiorito, Ralph

Research Interests: 

Dr. Fiorito's research interests include charged particle beam physics, diagnostics and radiation sources, and high energy astrophysics.


Dr. Fiorito was employed from 1973-1997 as a research physicist at the Naval Surface Warfare Center in Silver Spring, MD, where his research focused on the radiation from intense electron beams and their interaction with matter.  From 1978-1979 he was a visiting scientist at the Naval Research Laboratory (Division of Plasma Physics) and, in 1981, at the Lawrence Livermore National Laboratory (Beam Research Division).  From 1998-2001 he held the appointment of Associate Research Professor at the Catholic University of America in Washington, DC, and in 2001 joined the faculty of the Institute for Research in Electronics and Applied Physics at the University of Maryland, where he is presently a Senior Research Engineer.

Dr. Fiorito serves as a research advisor to graduate students as well as other IREAP faculty members and has given a number of invited lectures on charged particle beam physics in ECE courses and at the U.S. Particle Accelerator School.


Dr. Fiorito did his graduate studies at the Catholic University of America, Washington, DC (M.S.E.  Space Science and Applied Physics; Ph.D. Physics) and did postgraduate studies at the University of Maryland, College Park.

Honors and Awards: 

Dr. Fiorito was a co-recipient of the Faraday Cup Award in 1993 for the invention and development of Optical Transition Radiation Beam Emittance Diagnostics and in 1995 he received the Navy Civilian Service Award for his work in charged particle beam technologies.

Professional Memberships: 

Dr. Fiorito has collaborated with many national and international research institutes, including Los Alamos, Lawrence Livermore, Argonne, Oak Ridge, Jefferson, and Stanford (SLAC) National Laboratories, NASA’s Goddard Space Flight Center, the Paul Scherrer Institut in Switzerland, and the Tomsk Polytechnic University in Russia.

In 2003 Dr. Fiorito was elected a fellow of the American Physical Society (Division of Beams) for his contributions to the fundamental understanding and applications of transition, diffraction, and parametric x-radiation from charged particles.
