Description
Depolarisation of polarised collider beams, due to the strong electromagnetic fields of the bunch-bunch collision at the IP, is important to understand for the precision physics goals of future e+e- colliders. Beam parameters are generally chosen to maximise the collision luminosity whilst minimising non-linear effects from strong IP fields. Here it will be shown that luminosity can be further enhanced by a judicious choice for the relative longitudinal position of the beam waists. A simulation study of the beam waist optimisation on depolarisation will be presented. The possibility of higher order, non-linear depolarisation effects will be discussed.
