Description
The most important task of LHC or subsequent ILC is to find the Higgs particle and study its property. Since the degree of accuracy is much better in the latter case we have to think that the two machines are complimentary to each other.
In the usual electron-positron collider, the way to produce Higgs boson is to rely on the reaction e(+)e(-)-->H+Z. You produce Z boson together with H thus loosing almost 100GEV. The way to get around this loss is to use photon-photon collider. In the theoretical side, almost all the natural models (ST, MSSM, NMSSM ,etc) support Higgs mass of less that 170GEV. It is, therefore, very efficient to build a photon- photon collider for the purpose of Higgs factory.
I would like to propose this photon-photon collider as a precursor ( not as an alternative) to ILC. We will be able to cut the cost as much as half of ILC and also will be able to avoid all the complicated issues related to the positron beam.
