Description
The base-line positron source of the future International Linear Collider (ILC) is polarized and designed for an operation with electron drive beam energies between 150 GeV and 250 GeV (corresponding to 300 GeV up to 500 GeV CM energies). However, running at CM energies below 300 GeV reduces the positron yield substantially; running at Ecm = 1 TeV implies a low degree of positron polarization. The simulation results of yield and polarization at the positron source will be presented for these two "extreme" energies. The possible modifications of the helical undulator will be discussed.
