Electron scattering from a tensor polarized2H internal target

Abstract

An experiment (NIKHEF 91-12) is described which measures the spin dependence of the (e,e) and (e,e′p) reactions for polarized deuterium and unpolarized electrons, using the Internal Target Hall facility at the Amsterdam Pulse Stretcher Ring at NIKHEF. Tensor polarized deuterium is produced in an atomic beam source and injected into a storage cell target. Polarimeters are used to monitor the target polarization. A large acceptance non-magnetic detector system is used for the electron-proton (deuteron) coincidence measurement. It is demonstrated that these techniques result in low backgrounds due to scattering from species other than the polarized target gas and allow for fast and flexible orientation of the target spin. Specific issues such as interfacing the experiment to the storage ring and monitoring the performance of the target system are discussed in detail.
