Description
It is very likely that due to the cost “optimization” the ILC will have only one
detector and no further energy upgrade. This scenario with a long run time at the
energy 2E<=500 GeV only strengthens the case of the photon collider. In any case, it
is very important to develop a design which allows the best possible parameters of
the photon collider. The gamma-gamma luminosity is determined only by the geometric
e-e- luminosity which depends on beam emittances. Although the gamma-gamma luminosity
with damping rings optimized for e+e- collsions will be sufficient for good physics
but its further increase is very desirable, if it is technically possible and cost
not too much. In this talk I consider ways of increasing the gamma-gamma luminosity
from 2-3 times (by optimizing damping rings) to more than one order of magnitude
(using a laser cooling). This will allow to measure the Higgs self interaction and to
study many other processes at a new level of accuracies.
