History
In 2005, the Florida A&M Department of Physics established its presence at Innovation Park, a university-related research and development campus in Tallahassee, investing in the Center for Plasma Science and Technology (CePAST). The center has become one of the premier research facilities in the state of Florida; its scope was and is the study of plasmas, substances which are generally considered the ‘fourth state of matter’.

CePaST is home to a highly successful team of faculty, students, and researchers dedicated to new science and novel applications of theoretical, experimental, and computational plasma physics.  Major programs include:

•    High Energy Density Physics

•    Remote sensing research to enhance the nation’s defensive capabilities

•    Fusion and plasma research 

•    Developing advanced materials for use in defense and technological applications

•    Researching efficient computational algorithms in support of plasma and photonic physics

 The center is the flagship of FAMU’s commitment to comprehensive research excellence with technological impact.

The 32,000-sqft facilities include: student study areas, a computer cluster, a laser plasma lab and space for Florida’s first fusion facility. Faculty members, along with graduate and undergraduate student researchers are dedicated to innovative  applications of theoretical, experimental and computational plasma physics.


Mission
The strategic mission of the FAMU Center for Plasma Science and Technology (CePaST) is to produce world-class scientific and technological innovation in theoretical, experimental, and computational plasma physics and photonics.  The goals of the center are to:

•    Provide tools to enhance the nation’s security against domestic and foreign threats

•    Support the development of alternative sources of clean and sustainable energy

•    Conduct basic research on plasmas and advanced materials under extreme conditions

•    Provide a pool of highly trained men and women to broaden the nation’s scientific workforce.


These goals will be achieved through a broad spectrum of interdisciplinary research activities inclusive of research on remote sensing; fusion; carbon-based nanoscience; advanced algorithms; laser-matter interactions; and fundamental atomic and molecular quantum mechanical phenomena.
