3.0 [Panel Preparation]{.underline}

Completed

3.1 Acquire the Cathode Lower Panel (ME-368224) as per the Panel Serial
Number at

the bottom of this traveler.

3.2 Clean the entire panel (both sides) with Ethyl Alcohol (Fermi Stk.
No. #1920-0600)

and a low-lint wipe (Fermi Stk No. 1660-2500) to remove any dirt, dusts,
oils, and

other foreign material on the panel.

> 3.3 Acquire FR-4 Isolation Strips (MA-368299 \[4ea\]) and clean with
> Ethyl Alcohol

(Fermi Stk No. 1920-0600) and a low-lint wipe (Fermi Stk No. 1660-2500).

3.4 Acquire the following gap bars; (MA-368292 \[1 ea\], MA-368293 \[1
ea\], MA-368294 \[1 ea,\]

MA-368295 \[1 ea\], MA-368296 \[1 ea\], and MA-368297 \[1 ea\]) and
clean with Ethyl Alcohol

(Fermi Stk. No. #1920-0600) and a low-lint wipe (Fermi Stk No.
1660-2500) to remove any dirt,

dusts, oils, and other foreign material. Clean out the grooves in the
gap bars with cotton swabs

dipped in the ethyl alcohol.

3.5 Load one gap bar into the tape installation machine (368550)(or if
preferred, affix gap bar with

> Adhesive tape by hand) and affix 3M Scotch double side adhesive tape
> (368300) to the back of the
>
> gap bar. Trim both ends to fit. Trim out the holes and trim the tape
> where there is overlap on the side

of the gap bars. Continue until all gap bars are completed.

Completed

3.6 Mix glue (Epoxy Adhesive #2216 Parts A&B) in a 50/50 ratio using
approximately 30

grams of each. Allow the glue to sit for at least 30 minutes and no more
than 45 minutes.

3.7 When applying the Gap Bar (MB-368293) to the panel, be sure the gas
hole in gap bar

is located on the left side of the Panel Center line.

![](media/image1.wmf){width="4.30625in" height="1.2805555555555554in"}

3.8 Without removing the protective strip, align the gap bars along the
panel. Install

the pins (MA-368941) through the holes in the gap bar and into panel to
make sure

the gap bar holes and panel holes align.

3.9 Remove Gap Bars from the panel and remove the adhesive tape
protective strip.

3.10 Apply glue (Epoxy Adhesive #2216 Translucent) with a small brush to
all the interfacing

ends of the gap bars to create a fillet between the Gap Bar and the
panel copper. Realign the

gap bars onto the pins. Continue installing gap bars in this way until
all gap bars are installed

onto the panel. Ensure all alignment pins are removed from the gap bars
once they are

correctly taped in place.

3.11 After gap bars have been taped in place, clamp the gap bars for a
minimum of two hours.

**Note(s):**

**Panels must be glued and clamped the same day the Gap Bars are
installed!**

**During the installation of the gap bars, ensure correct placement of
the**

**gap bars as per the angle cut on the gap bar ends.**

**During the installation of the gap bars, visually check all four
corners to ensure**

**proper fit of gap bar interfaces.**

**Ensure the panel is covered with Mylar when the panel is not being
serviced**

4.0 [Panel Gluing]{.underline}

Completed

**Note(s):**

**The gluing of the Cathode Panels requires two days. On one day, one
Upper and**

**two Inner Panel sides will be glued. On the following day, one Lower
and the other**

**two sides of the Inner Panels will be glued.**

**On the day this Lower Cathode Panel is NOT being glued, place it on
the Cathode**

**curing table in the proper order according to the drawing below step
5.3.**

> 4.1 Transport the Cathode Lower Panel with gap bars installed to the
> Panel
>
> Gluing Station. Install the Cathode Panel onto the Gluing Station work
