Polarized Positron 2011 - Proceedings of the 6th Annual Workshop (Electronic book text)

This volume is a collection of the contributions to the 6th Annual Workshop on Polarized Positron held in China. It provides updated information on polarized positron source R&D efforts for future high energy linear colliders and other research activities related to the polarized positron studies.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 ILCCLIC e+ generation working group for all schemes Status of the CDR for CLIC and TDR for ILC Polarized electron sources
