Prof. Aharon Friedman 

Prof. Friedman is a veteran scientist and winner of several scientific awards. He was conducting pure and applied research and teaching in academia and governments laboratories until 1996. At that time, he left academia and founded Fortress Technologies – a communications security company (Cyber). Under his management Fortress grew to become the sixth largest company in the Tampa bay area. Fortress was and still is the largest provider of wireless network security to the US Department of Defense.

In the beginning of 2013 Prof. Friedman decided to retire from his corporate management role. He and his wife came back to Israel.  In Israel, Prof. Friedman took the role of the Head of Ariel University’s Schlesinger Compact Accelerator Center. In this role he helped revive the center. He is now leading several major new scientific projects as well as an ongoing one.

Prof. Friedman is also a member of the Department of Electrical Engineering in Ariel University.

Professor Yuri Lurie

Academic degree: Associate Professor

Position Researcher, Associate Professor of the Department of Electrical and Electronic Engineering, Ariel university

Work ExperienceProf. Yuri Lurie works in Ariel university (former college of J&S) since 1999.

Current research:

Research interests of Prof. Yuri Lurie include theoretical study of relativistic free-electron THz radiation sources, utilizing short picosecond and sub-picosecond electron bunches produced by a photocathode RF-LINAC. The research is currently concentrated on investigation of the so-called “Negative mass instability” taking place in strong, over-resonance focusing magnetic field combined with helical undulator, and possibility for its realization in free-electron sources. This enables formation and holding of ultra-short, dens electron bunches, what results in effective emission of strong THz radiation.
