Polarized Positron 2011 - Proceedings Of The 6th Annual Workshop

This volume is a collection of the contributions to the 6th Annual Workshop on Polarized Positron in China. It provides an important updated to couple Linear Collider (ILC+CLIC) aimed polarized positron source R&D efforts to more general polarized positron related community with the aim of advancing polarized positron studies through exchanges and collaborations. The topics covered include: positron beams for linear colliders, but not limited to it, with the main items listed below: Polarized gamma ray generation; High degree Polarized positron generation from compton scattering both ring and linac based; High degree polarized positron generation from undulator radiation; Stacking and accumulation of the polarized beam from compton regime; Polarized beam transport, control and acceleration; Channelling radiation and applications; Physics applications of polarized positrons; Various high intensity positron sources (include conventional); For other future colliders (SuperB for example); Positron generation target issues; Physics applications of high quality X-rays and gamma - rays; Polarimetry at the e+ source; The positron capture section and the photon collimation; Review the activities of the "ILC - CLIC e+ generation" working group for all schemes; Status of the CDR for CLIC and TDR for ILC; and, Polarized electron sources.
