    keyword=Beam problem, so did EPR.

    At 5:37, since the accelerator are experiencing some problems to deliver beam, I performed an EPR measurement with the target in reference cell position.

    The polarization is 39.2% but there is 1.6% (absolute) deffirence between the down and up sweeps.

    So it is better to perform EPR measurement when target is at low position: pol. 3He position or pick-up coils position.

    I did it to save some time.
