Özet:

 

The future high energy e e colliders, together with the  complementary g g option, will offer possibilities for both  discovery and precision physics.  The uncertainty on the initial beam  polarizations contributes to the systematic errors in each case.   Therefore, it is crucial to obtain the precise beam polarizations by  independent measurements.  The e g \rightarrow n W process in  the e g mode can be used to experimentally determine the  polarization of the initial e beam.  This note addresses the  feasibility of making such a measurement with a relative statistical  error of one percent.  Generator and detector level MC tools are used  to obtain a realistic simulation of the signal and background  processes at the future CLIC test facility running at \sqrt{s} = 150  GeV. We estimate about 8 months of data collection time by combining  the muon and electron channels.
