**[GENERAL NOTES:]{.mark}**

-   [All screws installed in the vacuum and cryogenic space must have
    some form of additional protection from working themselves loose
    during thermal cycling. The use of Loctite 242 or 245, or Stycast is
    recommended for this purpose.]{.mark}

**(Complete Above Ground)**

1.  [Carefully remove all shrink tubing from cable leads.]{.mark}

2.  [If cable labels are place where they will interfere with the
    splicing operation (e.g. at the end of the leads), then additional
    labels should be applied at a position on the cable where they will
    not interfere with the splicing operation. In order to apply new
    labels, it may be necessary to remove ground wrap which is holding
    the wire bundles together. If this is the case, be sure to remove
    only what is necessary. The labels at the ends can be removed in the
    tunnel, after the length of the lead is correctly
    determined.]{.mark}

3.  [All leads should be dressed to remove solder/weld excess.]{.mark}

4.  [Verify that the bus leads coming out of the IP-end of the Q2 magnet
    are correctly wrapped together. You may find them ground-wrapped
    separately, instead of together. If this is the case, remove the
    individual ground wraps, and then wrap the two together with one
    layer 2/3 lapped of Kapton (MA-292722, or equivalent).]{.mark}

5.  Install Vacuum Outer Shell Sleeve (ME-390322) and Vacuum Vessel
    Bellows Assembly (Provided by CERN) as per Q1 to Q2 Main Assembly

    to be spliced, between each main lead.

5.  Place solder fixture (MD-430138) around both lead splices.

6.  Screw solder fixture together around splices.

7.  [If desired, add an additional temperature measuring device (e.g.

    monitoring the temperature. [Tighten screws as the solder is
    softening, so that the fixture is completely closed when the solder
    is completely melted.]{.mark} When the solder has melted, turn off
    the heater [controller]{.mark}. The solder typically melts at about
    220°C, [but the temperature should be held at 235°C for one
    minute.]{.mark} Do not allow the temperature to exceed 240°C.

9.  Monitor the temperature during cool-down, [and let splice cool to \~
    40°C]{.mark}. [To monitor the temperature, unplug the heating
    element, and then turn the controller back on]{.mark}.

10. After cooling [(to \~ 40°C)]{.mark}, remove the splices from the
    fixture. **[NOTE: It is easiest to remove the splices while the

    temperature before removing the leads from the fixture.]{.mark}**

11. Clean exterior of splices with Tech spray and Scotch Brite or
    equivalent. Wipe down with Kay-dry or equivalent.

        Wrap each splice separately, using one wrap of 50 um thick by
        9.5mm wide Kapton (MA-292722) with 50% overlap as shown in
        detail E.
