Design Concept and Parameters of a 15 T $Nb_{3}Sn$ Dipole Demonstrator for a 100 TEV Hadron Collider

FNAL has started the development of a 15 T $$Nb_{3}Sn$$ dipole demonstrator for a 100 TeV scale hadron collider. This paper describes the design concept and parameters of the 15 T $$Nb_{3}Sn$$ dipole demonstrator. The dipole magnetic, mechanical and quench protection concept and parameters are presented and discussed.
