    keyword=RVDC plot

    The U2 plane wire 1-96 are connected to the cables for U1 wire 1-96, and the efficiency plot is shown for Run 20483. Run 20481 was taken before we changed the cables.

    The efficiency of U2 wire 1-96 of Run 20481 has the same shape as that of U1 wire 1-96 of Run 20483. So I think the efficiency problem is not caused by the electronics between the cable to the TDC.

    The wire 95 and 96 on U2 of Run 20483 having bad efficiency is possible caused by bad connection.
