[SLAC] [SLAC Pubs and Reports] SLAC-PUB-10407Positron Transmission and Polarization in E-166 Spectrometer Abstract The proposed experiment E-166 is designed to demonstrate the possibility of producing longitudinally polarized positrons from circularly polarized photons. It utilizes a low emittance 50 GeV electron beam passing through a helical undulator in the FFTB. Circularly polarized photons generated by the electron beam in undulator hit a target and produce electron-positron pairs. Spectrometer after positron production target includes a solenoid and bending magnets to deliver polarized positrons to a reconversion target. The results of the simulation indicate that positron transmission efficiency of 1...3 % with beam polarization of 60...80 % can be obtained in spectrometer. (Equations render on Windows, Mac OS, AIX, Linux, Solaris, and IRIX with the techexplorer plug-in.)
