Description
At the International Linear Collider (ILC) both beams --electrons and positrons-- will be polarized since the positron source is based on a helical undulator. The electron beam passes the undulator which is located at the end of the main linac. So the undulator parameters are strongly coupled to the centre-of-mass energy. The positron polarization has to be optimized for each energy depending on physics
requirements taking into account the acceptable thermal, mechanical and radiation load at the positron source components.
The options are discussed in the talk.
