    keyword=Post-experiment survey and target tests

    Beam off at 7 am (after the neutron detector test).
    With RADCON support, Vince put the Photodiode in the target chamber. Patricia
    got very good EPR signal. First few EPRs showed clear sign of masing and then it became flat. Patricia completed EPR-NMR calibration.
    Target survey started after that (~8 am). First survey with oven on (170 degree C).
    Then with oven off and after cooling down to near room temperature.
    We (Vince and I) took out the pol. He3 cell and target ladder after the target survey.
    Vince put in the Compass for target field survey. It is still going on. Plan is to survey
    field for 0, 180 and 270 degrees (repeat once if time allows). Then took out the
    Compass, the reference cell and install water cell. Vince and Jadeep will do water calibration over the weekend.
