ARIES Workshop on Energy Efficient RF

18 Jun 2019, 12:40 → 20 Jun 2019, 12:05 Europe/Stockholm

10132 Häggsalen (Ångström Laboratory)

Claude Marchand (CEA Saclay), Dragos Dancila (Uppsala University), Juliette Plouin (CEA Saclay), Roger Ruber (Uppsala University)

ARIES, Uppsala University, and CEA organize an international workshop on concepts for energy efficient RF power generation for accelerators. Experienced researchers and leading companies in the field of RF power generation and related technologies will explore the technical challenges emerging from the design of new accelerators and to match them with state-of-the-art industrial solutions for RF power generation.

The workshop will focus on methods, technologies and experiences in energy efficient electron tube devices and solid-state amplifiers.

Through knowledge exchange between research institutes and commercial partners, the workshop will address technical challenges shared by European research institutes collaborating in TIARA.
