    16:00 1/2 Wave is out.
    17:50 Right Arm ps1 from 2 to 1 as suggested by RC. Deadtime is 32%.
    19:47 Start to do dilution runs. Target moved to C12_40
    19:51 Bleed-through = 0.5%
    20:00 Melissa do T2 test on carbon target
    20:35 Target to dummy
    20:45 Target to HOME
    21:15 Target to top NH3
    21:29 P0=1.391, Pol=35% without beam, 31% in beam(estimation)
    21:32 Ask beam for 50nA, start taking production.
