| The International Linear collider (ILC) is a e+ e- linear collider at center of mass energy up to 1 TeV. At the interaction point, the beam shape has to be flat in the transverse space to maximize the luminosity compensating the energy spread by Beamstrahlung. The flat beam is obtained by asymmetric emittance in x and y made up by radiation damping with a 3 km damping ring. We propose a new method to make the asymmetric emittance based on emittance exchange techniques using the two beamlines such as Round to Flat beam transformation (RFBT) and Transverse to Longitudinal Emittance exchange (TLEX). In KEK STF facility the RFBT experiment has been performed but the results are not as expected due to a significant emittance growth by space charge effect. We studied the emittance growth compensation by space charge effect by the envelope matching in the STF injector. The results will be reported. |
