 mainline concepts — tokamaks and mirrors. 3 The following table 

 identifies the principal tokamak and mirror fusion devices, their 

 locations, and their fiscal year 1984 budgets including funds for 

 both operating expenses and capital modifications.

^The two mainline magnetic confinement approaches are categorized 

 as closed and open. Closed magnetic confinement systems are 

 doughnut-shaped devices generally referred to as toroids. There 

 are several kinds of toroidal devices including tokamaks, stella- 

 rators, and compact toroids. Because of promising experimental 

 results, tokamaks are the toroidal devices being examined most 

 extensively, both in the United States and in other countries. 

 Open magnetic confinement systems are generally referred to as 

 mirrors. They consist of a long tube with large magnets at each 

 end that reflect back and contain the fusion fuel.
