    keyword=Target polarization: 37.7%

    Target polarization measured at 1038 using NMR.

    This was performed at a higher temperature (240C) and an attempt was made to use the new coil that reads the upper chamber polarization & density. The upper chamber data was not saved. No attempt at EPR was made at this time.

    Pumping Chamber Temp: 240 +_ 1 Target Chamber Temp: 27.1 Lockin Sensitivity: 300mV Time Constant: 10ms RF Current (mVpp on scope): 324mVpp

    NMR Up = -85.2 mV NMR Down = -84.1 mV

    Using what I believe is the most conservative constant, we get 37.7% and 37.2% for up and down. Using another constant that I believe is closer to the reality, we get 39.6% and 39.1%.

    My conclusion is that we are still rising, but we are slowing down.
