Estimated parameters for linac-ring colliders

Discussion of physics goals for TeV gamma-proton and gamma-nucleus colliders

Recommendations for future collider development

Abstract

The first Part contains the invited talk given at the First International Workshop on Linac-Ring Type ep and $gamma$p Colliders (9-11 April 1997, Ankara, Turkey). Four known types of colliders, which may give an opportunity to achieve TeV center of mass energies in the near future (10-15 years), are discussed. Parameters of the linac-ring type e-p, $gamma$-p, e-nucleus and $gamma$-nucleus machines are roughly estimated. Some speculations on TeV scale physics are given. The physics goals of the TeV energy $gamma$-p and $gamma$-nucleus colliders are considered. Information about the Ankara'97 Workshop, including Workshop Conclusion and Recommendations, is presented in Part II. Finally, an Appeal to ICFA, ECFA and ACFA is presented in Part III.
