TESLA-N: Project for a Polarized Electron-Nucleon Scattering Experiment at TESLA — •Rezo Shanidze and Erhard Steffens — Physikalisches Institut der Universität Erlangen-Nürnberg, Erwin-Rommel Str.1, 91058 Erlangen
TESLA-N is a project for a polarized electron-nucleon scattering experiment at TESLA electron-positron linear collider. Longitudinally polarized electrons can be accelerated and directed to the solid state target with longitudinal or transverse polarization in parallel to the main beam of the e+ arm of an electron-positron collider. With a small fraction of the total accelerator current experiment can achieve luminosities that are about two orders of magnitude higher than those expected of other experiments at comparable energies.
A main goal of the experiment is the precision test of QCD in the spin sector. This will include the precise measurements of the x- and Q2-dependence of the experimentally totally unknown quark transversity distributions as well as measurements of polarized gluon distribution and quark helicity distributions in the nucleon. The possibilities of using unpolarized targets and of experiments with a real photon beam turn TESLA-N into a versatile next-generation facility at the intersection of particle and nuclear physics.
The conceptual design of the TESLA-N detector and simulation of its performance will be presented.
