The European Spallation Source signs agreement for development of novel technology that could bring considerable energy savings for the facility.

One of the agreements was signed with a consortium consisting of Thales Industries and the American company Communications & Power Industries (CPI) and the other with the provider of communication and electronic systems and products, L3. If proven to work, the new technology could mean substantial, (million EUR-level), energy savings for the research facility and be a game-changer for the RF industry.

Initial meetings between the US based companies and ESS, took place during a seminar set up by Business Sweden and Invest in Skåne in Washington DC during December 2013.

The initiative pioneers novel vacuum tube technology and would mean energy savings in the ESS linear accelerator (LINAC), also known as the facility’s engine. The LINAC is also the part of the facility that consumes the majority of the electricity so any energy savings that can be achieved there will translate directly into the reduction of operational costs. In comparison with the current alternative, this novel energy technology could mean power savings of between 10-20 % for the ESS and future facilities.

“The European Spallation Source will be the world’s first sustainable research facility. The development of this technique is highly related to our energy concept based on three Rs; Responsible, Renewable and Recyclable.” Says Mats Lindroos, Head of Accelerator Division and Accelerator project at ESS, “ The development and innovation fits very well into Responsible and in making the facility’s energy system as efficient as possible we are ensuring the responsible and sustainable approach.”

The cooperation agreement comprises the re-development of an old technology, i.e. IOT (Inductive Output Tube) to a potentially strong competitor to the currently developing technology such as the solid state (transistor) alternative. The development of pyrolytic graphite grid technology and the “on-the-shelf” availability of powerful solid-state RF amplifiers as pre-amplifiers are making the IOT of today a viable and advantageous alternative to the more traditional klystron technology.

Prototype development is underway. The production will begin in 2016, with delivery to CERN for testing in 2017 and early production of units delivered to ESS by 2019.

About the European Spallation Source - The European Spallation Source (ESS) is one of the largest science and technology infrastructure projects being built today. The facility is a multi-disciplinary research centre based on the world’s most powerful neutron source. The facility will be around 30 times brighter than today's leading facilities, enabling new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics.
