REPORT OF REACTOR CONCEPT IMPROVEMENT SUBPANEL 



1. Charge 



The purpose of the Subpanel is stated in its charge from the Summit 

 Working Group on Fusion: 



"Research on improved plasma confinement concepts, both 

 improved versions of the tokamak and alternative 

 geometries, has resulted in important advances in 

 physics understanding, as well as the development of 

 approaches that show significant promise of an improved 

 reactor product. To a considerable extent, these 

 programs are already conducted in a cooperative and 

 non-duplicative manner with different emphasis in 

 different countries and bilateral agreements where 

 appropriate." 



Charge: This Subpanel should identify other opportunities to 

 optimize this endeavor within the limits of resources." 



As part of the Subpanel for Near-Term Fusion Physics and Technology, the 

 focus is on the next 5 years. 



II. Scope 



The topics assigned to this Subpanel are: 



Tokamak Improvements 



Open Systems 



Alternative and Supporting Systems 



Inertial confinement fusion (ICF), though an important part of the fusion 

 programs of several Summit nations, is outside the scope of the Subpanel. 



Here Tokamak Improvements refers to those aspects of tokamak research 

 that could ultimately lead to major changes of configuration compared to 

 the large tokamaks of today. Examples are extreme non-circular cross- 

 section, or reliance on rf current drive. Open Systems refers to mirror 

 devices, and Alternative and Supporting Systems refers to toroidal 

 devices other than tokamaks (Stellarator/heliotron, RFP, EBT, Compact 

 Toroids).
