Positron transmission and polarization in E-166 spectrometer
- SLAC
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.
