Abstract
An apparatus for the measurement of the two transverse polarization components PT1 and PT2 of the positrons from polarized μ+ decay is described. It makes use of a stroboscopic method which cancels many systematic asymmetries and allows one to use muon stop rates in the order of up to 108 s−1. The experiment aims at an accuracy of ΔPT1=ΔPT2=3×10−3 and by that at an improvement of the existing limit by nearly one order of magnitude. With these results one will obtain an improved model-independent value for the Fermi coupling constant GF and more stringent limits to possible violations of time reversal invariance in a purely leptonic reaction.
