摘要：
We present a new method for precision measurement of the capture flux polarization of a polychromatic ( white), continuous cold neutron beam, polarized by a He-3 spin filter. This method allows an in situ measurement and does not require knowledge of the neutron beam wavelength distribution. We show that a polarimetry precision of 0.1% is possible.
