**[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 lower 13KA bus lead set coming out of the
    non-IP-end of the Q2 magnet is trimmed and insulated correctly. It
    should stick out from the bus housing no more than 25mm, and should
    have a Kapton, Nomex, glass tape and Kevlar string wrapping. If
    necessary, solder and then cut the lead to the proper length, and
    apply the following:]{.mark}

-   [One layer ½ lapped 3.5mm adhesive-backed Kapton, leaving a flap
    over the end.]{.mark}

-   [Nomex sheathing (part supplied by Fermilab, P/N TBD).]{.mark}

-   [Two layers of ½ lapped glass tape. The first layer should start
    from the end of the lead and work towards the magnet, and the second
    layer should go in the opposite direction. Both layers should have
    at least one width of tape directly on the Kapton near the bus
    housing.]{.mark}

-   [Fuse the ends of the glass tape to prevent the tape from
    unraveling.]{.mark}

-   [Apply Kevlar string in a similar manner to that described in step
    10.6.4 below.]{.mark}

5.  [Verify that the bus leads coming out of the IP-end of the Q3 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}

6.  Install Vacuum Outer Shell Sleeve (ME-390331) and Vacuum Vessel
    Bellows Assembly (Provided by CERN) as per Q2 to Q3 Interconnections
    with TAS Main Assembly (ME-390869). Position them so that they do

    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
    fixture is a little warm, so it is best not to let it cool to room
    temperature before removing the leads from the fixture.]{.mark}**

11. Using the tool provided (MB-430192), verify that the Q3 lead
    longitudinal position is correct.

12. Clean exterior of splice with Tech spray and scotch brite or
    equivalent. Wipe down with Kay-dry or equivalent.

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

14. Paint flux (Kester 135, MA-369911 or equivalent) on all surfaces to
    be soldered on the two top lead splice sets.

15. Add solder strips (MA-369904 or equivalent, 0.2 mm thick) to areas
    to be spliced, between each main lead.

16. Place solder fixture (MD-430138) around the two top lead splice
    sets. NOTE: the lower main bus lead splice will need to be protected
    from the heat from soldering the upper main bus leads. If necessary,
    add insulation between the soldering fixture and the splice below
    the fixture.

17. Screw solder fixture together around leads.

18. [If desired, add an additional temperature measuring device (e.g.
    handheld thermocouple).]{.mark}

19. Turn on resistive heaters, and wait for the solder to melt, while
    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.

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

21. After cooling [(to \~ 40°C)]{.mark}, remove the splices from the
    fixture. **[NOTE: It is easiest to remove the splices while the
    fixture is a little warm, so it is best not to let it cool to room
    temperature before removing the leads from the fixture.]{.mark}**

22. Using the tool provided (MB-430192), verify that the Q3 lead
    longitudinal position is correct.

23. Clean exterior of splices with Tech spray and scotch brite or
    equivalent. Wipe down with Kay-dry or equivalent.

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

```{=html}

6.  Insulate Splice Bundle.

    1.  Place one G-11 splice separator (MB-430084) between each of the
        splices as shown in section B-B.

    2.  Wrap entire splice bundle with one wrap of 50 um thick by 9.5mm
        wide Kapton (MA-292722) with 75% overlap surrounded by one layer
        of glass tape (item #7 on ME-430180) with 50% overlap as shown
        in detail E.

    3.  Fuse the ends of the glass tape to prevent the tape from
        unraveling. Use soldering iron to burn line over the last couple
        of wraps.

    4.  [Wrap entire splice bundle with Kevlar string (MA-369912, or
        equivalent) in a similar fashion to cartoon below (figure
        10.6.4-A). The spacing between each loop should be \~ 1.5 cm,
        and the string should be pulled tightly around the splice
        bundle. Apply Loctite to each cross-over to hold the string in
        place. The colors of the string in the cartoon below (figure
        10.6.4-A) show the way in which the string is wrapped, but the
        string should be one continuous piece, as much as is
        possible.]{.mark}

**[[Figure 10.6.4-A]{.underline}]{.mark}**

7.  Perform Corrector lead splices

        wire 100mm back from center of splice.

    3.  Using appropriate means, remove the varnish from the leads only
        in the areas to be soldered. See figure 10.7.3-A below.
