Energy Efficiency and Choice of Parameters for Linear Colliders
The cost of large high energy facilities is a matter of strong concern. Such facilities use very large amounts of electric power and a sizeable part of the total cost is directly related to that fact. It is therefore important to have a clear understanding of the factors that influence the power efficiency, i.e., the amount of power used per unit product, where product is the luminosity generated at a specified energy. The overall efficiency may be regarded as the product of the effciencies with which the parts of the system perform their functions: the efficiency with which raw grid power is converted to r.f. power, the efficiency with which r.f. power can be transmitted from source to load, the efficiency of conversion of r.f. power into particle beam power and finally the efficiency with which beam power is converted to luminosity.
