Design Studies for Flux and Polarization Measurements of Photons and Positrons for SLAC Proposal E166: An experiment to test polarized positron production in the FFTB

چکیده
We present results from design studies carried out to investigate measurements of the flux, spectrum and polarization of undulator photons for SLAC Proposal E166. A transmission Compton polarimeter is considered for measuring the photon circular polarization. We also present results for measuring the flux and spectrum of positrons produced by the undulator photons in an 0.5X0 Titanium target. And we present some considerations for use of a transmission Compton polarimeter to measure the circular polarization of bremsstrahlung photons emitted by the polarized positrons in a thin radiator.

Undulator-based production of polarized positrons
Full exploitation of the physics potential of a future International Linear Collider will require the use of polarized electron and positron beams. Experiment E166 at the Stanford Linear Accelerator Center (SLAC) has demonstrated a scheme in which an electron beam passes through a helical undulator to generate photons (whose first-harmonic spectrum extended to 7.9MeV) with circular polarization...
متن کاملThe E166 experiment: Development of an undulator-based polarized positron source for the international linear collider
A longitudinal polarized positron beam is foreseen for the international linear collider (ILC). A proof-of-principle experiment has been performed in the final focus test beam at SLAC to demonstrate the production of polarized positrons for implementation at the ILC. The E166 experiment uses a 1 m long helical undulator in a 46.6 GeV electron beam to produce a few MeV photons with a high degree...
متن کاملThe E166 Experiment: Undulator-Based Production of Polarized Positrons
A proof-of-principle experiment has been carried out in the Final Focus Test Beam (FFTB) at SLAC to demonstrate production of polarized positrons in a manner suitable for implementation at the ILC. A helical undulator of 2.54 mm period and 1-m length produced circularly polarized photons of first harmonic endpoint energy of 8 MeV when traversed by a 46.6 GeV electron beam. The polarized photons...
متن کاملPulsed Undulator for Test at Slac the Polarized Positron Production
Conversion system for polarized positron production [1] contains ~130 m-long helical undulator followed by thin target. Helical gammas radiated by primary high-energy beam in undulator transfer theirs polarization to the positrons and electrons at the high edge of energy spectrum. Selecting secondary positrons/electrons by energy, one can at the same time select theirs polarization (higher ener...
متن کاملPolarized Positrons at a Future Linear Collider and the Final Focus Test Beam
Having both the positron and electron beams polarized in a future linear e+e−collider is a decisive improvement for many physics studies at such a machine. The motivation for polarized positrons, and a demonstration experiment for the undulator-based production of polarized positrons are reviewed. This experiment (‘E-166’) uses the 50 GeV Final Focus Test electron beam at SLAC with a 1 m-long h...
