CONCLUSIONS JE’s ( IAEA CRP)• These first Joint Experiments have clearly demonstrated that small

tokamaks are suitable and important for broad international cooperation, providing the necessary environment and manpower to conduct dedicated joint research programmes.

• The contribution of small tokamaks to the mainstream fusion research such as edge turbulence, improved confinement, and diagnostics development can be enhanced through coordinated planning.

• The activities under this IAEA Coordinated Research Project are already paying visible dividends both in increased number of publications and improved collaboration between participating tokamak teams.

• Another important result of joint experiments is the improvement in understanding and communications between scientists from different countries, creating efficient team work both during experiments and data analysis.

Fluid Model of Electron Cyclotron Current Drive

Research Institute

12227-010 São José dos Campos, SP, Brazil

A theory was recently advanced to describe the dynamics of electron cyclotron current drive (ECCD) using a simple macroscopic model.

One expects to apply the model to the study of both instabilities in

ECCD and synergy effects with other current drive means.
