    * All the HV for dE and E planes are on.

    * The ADC spectrum are good for both dE and E sets.

    The missing ADC spectrum in dE-15R, 17R and 18R are because of the connection were not connected in between.

    * The HV for the MWDC is slowly turned up. No large drawing of the current == no broken wires (I guess).

    * The MWDC hit.wire have missing sections. Found the problems. ** The weight of the cables are pulling them down from the TDC in roc9 [putting the cable tiles to support the weight into three layers.see roc9] ** Switch out the cables from BigBite PP to LT (PP7-2, PP7-9 PP9-11 PP8-11) ** the problems are not yet fixed.

    some missing just appear and disappear from times to times. I guess I need a better method to deal with this.
