PPT-ILC Electron and Positron Sources

Wei Gai for the ILC e and e collaboration PAC review 2012 KEK Japan ILC site layout and location of e and e sources Page 3 The Baseline ILC Electron Source Electron source provides polarized electron beam and consists of all systems from source laser to 5 GeV injection to damping rings 325 MHz SHB. Positron Sources Positrons can be obtained from the b of radioactive isotopes, e.g. from 22Na according to the decay reaction 22Na Tzu-Cheng, Chuang. . (. 莊子承. ). Exchange student from.
