    keyword=3He + N2 pressure curves pt 2

    Before:
    3He Pressure Curve Run Summary
    N2 Pressure Curve Run Summary

    This morning:
    Helium:
    3040 0726:0736 1.5M Ref Cell, Empty 3 K 3 microA
    3041 0741:0751 2.0M Ref Cell, 3He, 35 7 K 1 microA
    3042 0753:0804 1.9M Ref Cell, 3He, 90 14 K 1 microA
    3043 0807:0817 2.4M Ref Cell, 3He, 140 21 K 1 microA

    i should have run the He pressure curves runs at a higher current. This is b/c we want to get data in "typical conditions" which is between 3-6 microA and the BCM aren't well calibrated @ low currents (<~ 3 microA?).

    Nitrogen:
    3044 0832:0841 2.1M Ref Cell, N2, 140 131 K 1 microA
    3045 0843:0852 1.5M Ref Cell, N2, 90 93 K 1 microA
    3045 0906:0917 2.3M Ref Cell, N2, 35 42 K 1 microA
