Radio frequency heating systems
CCFE has a long history in designing and building radio frequency (RF) heating systems on the JET and MAST tokamaks and has had a key design role for the ITER ion cyclotron resonance heating system for a number of years. Our complementary skills in operation and maintenance of such devices, and significant mechanical design experience on neutral beam systems mean we have amassed a wealth of applicable knowledge to such design tasks.
Capabilities
- Strong systems engineering approach to the development of design concepts through to manufacture
- Extensive knowledge of materials selection, processing and joining in a fusion environment
- Abiltiy to perform small scale trials in-house to verify novel design concepts and joining techniques
- Good links with local companies and institutions for collaboration in development of specialist material applications and measurement / inspection techniques
- Finite element modelling of thermal and structural load cases within which the antenna is expected to operate
- Modelling of RF structures and plasma edge behaviour in various operational phases to determine optimum mechanical and RF design
- Structural modelling of electromagnetic forces generated within the antenna during various disruption scenarios
- Extensive CATIA design facilities and expertise to bring together design solutions in a co-ordinated manner
Applications
- Design of ion cyclotron heating systems
- Design of ceramic load bearing nuclear windows
- Design of first wall structures
