    keyword=polarization drop explained

    The measurement that was reported at 03/12/06 22:42 reported a drop in the polarization. This drop in polarization is now at least partially understood.

    The polarization measurements recorded correspond to a measurement with the time stamp of 22:30. There was another measurement 4 minutes earlier (at 22:26). The measurement at 22:26 indicates a higher polarization, much more in line with what we would expect.

    Whenever a polarization measurement is made, there is a loss associated with the flipping of the spins. There may be other effects, but this loss is most likely the culprit for the decreased polarization.

    The size of the loss seems quite large, but this could be due to a number of factors that we are currently studying.
