In order to match the precision requirements at the ILC both beams polarized have to be manipulated. In the talk a few aspects in this context are discussed, for instance, helicity flipping and spin tracking at the spin rotator, as well as, resonance depolarization via an RF kicker.

The P2 experiment at MESA requires sub-percent accuracy of the beam poalrization measurment. Several polarimeters will be needed to obtain a sufficient redundancy of the experiemnt. The two main polarimeters will be a double scattering device at low energy and a new type of Möller polarimeter. The latter can operate online directly in front of the experiment. The status of the two...

At the planned International Linear Collider (ILC), the longitudinal beam polarization needs to be determined with an unprecedented precision. For that purpose, the beam delivery systems (BDS) are equipped with two laser Compton polarimeters each, which are foreseen to achieve a systematic uncertainty of 0.25 %. The polarimeters are located 1.6 km upstream and 150 m downstream of the e^+e^-...
