E-166 Experiment

E-166 Experiment. E-166 is a demonstration of undulator-based polarized positron production for linear colliders. E-166 uses the 50 GeV FFTB beam in conjunction with 1 m-long, helical undulator ( ? = 2.4 mm, ID = 0.9 mm) to make 10-MeV polarized photons. These photons are converted in a
