Electron and positron sources (2)•LCRD 2.37: Undulator Based Production of Polarized Positrons (William Bugg)•LCRD 2.40: Development of Polarized Photocathodes for the Linear Collider.(Richard Prepost)G. Gollin, 1/10/04 ALCPG04 <strong>Accelerator</strong> R&D <strong>summary</strong> 72
<strong>Accelerator</strong> Physics LCRD 2.37 (funded FY03, $25k)Undulator Based Production of Polarized Positrons for Linear Colliders(SLAC Experiment E-166: presented by JC Sheppard)S. Berridge, W. Bugg, Y. Efremenko, T. Handler, Y. Kamychkov, S.Spanier, University of TennesseeC. Lu, K.T.McDonald. Princeton University• E-166 uses the 50 GeV FFTB beam in conjunctionwith a 1 m-long, helical undulator (λ = 2.4 mm,ID = 0.9 mm) to make 10-MeV polarized photons.Concept: Balakin and Mikhailichenko (1978)•These photons are converted in a ~ 0.5 rad. len. Thicktarget into e+ (and e-) with ~ 50% polarization.•The polarization of the positrons and photons willbe measured.• E-166 scheduled to run in Oct. 2004.Hardware: Silicon calorimeters (U.Tennessee),Aerogel Cerenkov, Positron transport magnets (Princeton).G. Gollin, 1/10/04 ALCPG04 <strong>Accelerator</strong> R&D <strong>summary</strong> 73
