    keyword="new" MWDC settings

    After looking at the results of runs 2968(nominal) and 2969 (+50V), we have decided to increase the MWDC voltage at the wires by +30V, +50V, and +20V for chambers 1, 2 and 3, respectively. This means the new goals are 1630V, 1770V, and 1785V.

    A simple calculation shows that simply increasing the set-points by these amounts will account for most of the shift. And so the expected setpoints are:

    8.0 to 1890
    8.1 to 1890
    8.2 to 1845
    9.0 to 1660
    9.1 to 1635
    9.2 to 1842
    9.3 to 1799
    9.4 to 1891
    9.5 to 1888
    9.6 to 1659
    9.7 to 1804
