Helyssen is a CRPP Spin-off and has its Labs at the EPFL

Develop future generation plasma sources through research

Dr Philippe Guittienne founded Helyssen in 2003 to develop and commercialize application licenses on proprietary technologies.  Since inception, Helyssen research lab is located in the Centre de recherches des plasmas (CRPP) in EPFL and collaborate closely with Dr Hollenstein’s industrial plasma group.

Helyssen focuses on designing high efficiency inductively coupled and wave heated RF plasma sources.

Major milestones include:

CTI grant of CHF 100’000 in 2006 for best innovative company
Patents application for Helyssen’s antennas
