    keyword=High statistic 3he cell run 2631 with raster MCC 4.5x4.5

    High statistic 3he cell run 2631 with raster MCC 4.5x4.5 Previously got for other raster sizes

    Run 2622: nominal "6x6" raster (i.e. asked MCC for 6x6) T3rate=12.3 Hz, I=1.1715 uA, rate/current = 10.50+/-0.08

    Run 2623: nominal "3x3" raster T3rate=11.4 Hz, I=1.1896 uA, rate/current = 9.58+/-0.10

    Now

    Run 2631: nominal "4.5x4.5" raster T3rate=11.2 Hz, I=1.18 uA, rate/current = 9.49+/-0.08

    So agreement between "3x3" and "4.5x4.5". Run 2631 beam positions where Ax = -.6 Ay = -1.5 Bx = -.6 By = -1.0
