Description
Summary:Recent modifications to the LAMPF Biomedical Channel1 have improved versatility for stopping pion and muon physics experiments. High muon polarization was achieved by favorable kinematic selection of the decay muons. This polarization has been measured and found to be close to the design expectation of about 85%. The Hanle method2 was employed to measure the polarization by observing left-right decay asymmetry at right angles to the beam with small precession fields (0-50 gauss). This technique is particularly suitable for high-intensity muon beams.
