Polarized Positron 2011 - Proceedings Of The 6th Annual Workshop (ePub)

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 generationHigh degree polarized positron generation from Compton scattering both ring and linac basedHigh degree polarized positron generation from undulator radiationStacking and accumulation of the polarized beam from Compton regimePolarized beam transport, control and accelerationChannelling radiation and applicationsPhysics applications of polarized positronsVarious high intensity positron sources (include conventional)For other future colliders (SuperB, for example)Positron generation target issuesPhysics applications of high quality X-rays and gamma-raysPolarimetry at the e+ sourceThe positron capture section and the photon collimationReview the activities of the “ILC–CLIC e+ generation” working group for all schemesStatus of the CDR for CLIC and TDR for ILCPolarized electron sourcesContents:Physics Applications of Polarized Positrons (S Riemann)Positron Source for International Linear Collider (Wei Gai and Wanming Liu)On the Parameters of International Linear Collider Positron Source (Waming Liu, Wei Gai, Sabine Riemann and Andriy Ushakov)Polarized Positrons for the ILC — Update on Simulations (A Ushakov, O S Adeyemi, G Moortgat-Pick, F Staufenbiel and S Riemann)Why K-Factor in ILC Undulator Should Be Small (Alexander A Mikhailichenko)Status of Prototyping of the ILC Positron Target (J Gronberg, Craig Brooksby, Tom Piggott, Ryan Abbott, Jay Javedani and Ed Cook)Heat Load and Stress Studies for an Design of the Photon Collimator for the ILC Positron Source (F Staufenbiel, S Riemann, O S Adeyemi, V Kovalenko, L Malysheva, A Ushakov and G Moortgat-Pick)Lithium Lens for ILC (Alexander A Mikhailichenko)Spin Tracking at the ILC Positron Source (V Kovalenko, O S Adeyemi, A Hartin, G A Moortgat-Pick, L Malysheva, S Riemann, F Staufenbiel and A Ushakov)The Truly Conventional Positron Source for ILC (Tsunehiko Omori, Junji Urakawa, Tohru Takahashi, Shin-Ichi Kawada, Sabine Riemann, Wei Gai, Wanming Liu, Jie Gao, Guoxi Pei, Natsuki Okuda and Andriy Ushakov)Multi Bunch Gamma Ray Generation Experiment at ATF (Tohru Takahashi)Positron Source Using Channeling with a Granular Converter (P Sievers, C Xu, R Chehab, X Artru, M Chevallier, O Dadoun, G Pei, V M Strakhovenko and A Variola)Compton e+ Source Overview (RING + ERL + LINAC) (Junji Urakawa)Compton Ring with Laser Radiative Cooling (E Bulyak, J Urakawa and F Zimmermann)BEPCII Positron Source (Pei Guoxi, Sun Yaolin, Liu Jintong, Chi Yunlong, Liu Yuncheng and Liu Nianzong)Research of Compact X-Ray Source based on Thomson Scattering at Tsinghua University (Yingchao Du, Lixin Yan, Jianfei Hua, Qiang Du, Houjun Qian, Chen Li, Haisheng Xu, Wenhui Huang, Huaibi Chen and Chuanxiang Tang)
