Resumen:
Un centro de investigación británico que está desarrollando una red de calentamiento óhmico (OH) está interesado en desarrollar su tecnología en nuevos sectores mediante un acuerdo de licencia. La tecnología es una red de conmutación que conecta la fuente de energía impulsora al tokamak JET para inducir y mantener la corriente de plasma, elevando la temperatura del plasma hasta alrededor de 20.000.000 °C. La red consiste en interruptores de apertura y cierre de corriente, un circuito contador de pulsos, resistencias de conmutación y dispositivos de protección y seguridad. El aparato puede desarrollarse potencialmente para su uso en otras tres aplicaciones: evaluación de componentes de circuitos industriales, aplicación óhmica de alta corriente y tensión in situ o adquisición de datos a gran velocidad para análisis.

Summary:
UK research organisation developing an Ohmic Heating (OH) Network is looking to develop its technology in to new sectors via a licencing agreement. This technology is a switching network that connects the driving energy source to the JET tokamak to induce and maintain the plasma current. The network consists of high current opening and closing switches, a counter-pulse circuit, commutating resistors, and various safety and protection devices already installed.
Description:
UK research organisation developing an Ohmic Heating (OH) Network is looking to develop its technology in to new sectors via a licencing agreement. Essentially the Ohmic heating (aka resistive heating, or Joule heating) is used to induce and maintain the plasma current in the JET tokamak; raising the temperature of the plasma to around 20,000,000 °C. The OH network constructed at CCFE consists of high current opening and closing switches, a counter-pulse circuit, commutating resistors, and various safety and protection devices and their controls.

The switching network can withstand currents of up to 40 kA and has an (80bar) air blast system to eliminate the arc when the switch is opened. A counter-pulse circuit is installed in case of arc re-strike, which charges a bank of high storage capacitors (1.2 mF at 25 kV).

The OHC is currently used to induce and maintain the plasma current in the JET nuclear fusion tokamak however the apparatus could potentially be developed for use in three broader applications in various sectors. These are the testing of industrial circuit components (e.g switches and busbars), the high current or high voltage OH application onsite or high-speed data acquisition for analysis.
Advantages and Innovations:
The OH network currently supplies approximately 1 MW of power to the JET tokamak, and is capable of producing plasma currents of up to 5 million amperes. The facility is thus unique in its high power capability and as such is suitable for industrial-scale testing and OH applications, while the nature of its intended use make it suitable for high-speed data analysis applications as well. The purpose-built facility has been used extensively for high-power fusion applications. It is rigorously maintained and tested by experts. Safety and protection devices are already installed.

Partner sought

Type and Role of Partner Sought:
Looking for research and development organisations from academia or industry who operate in fields not related to fusion energy who are willing to collaborate and develop this technology in these new sectors via a licencing or research cooperation agreement. These organisations need to be focusing on the wider exploitation of this technology with a view to commercialisation.
