**Detector Assembly Procedure**

# U/V Frame Preparation

1.  Choose a good frame.

    a.  Look at channels 1 and 20 from an edge view and ensure they are
        vertical. If not, set frame aside and choose another.

2.  Prepare New Frame.

    a.  Take frame, aluminum mask and 0.5mm mechanical pencil to marble
        table.

    b.  Place long edge of frame on table with detector active area
        (gray area on picture) against table and gently push mask
        against detector.

        i.  Gently place graphite from pencil on exposed fins.

            1.  Move mask along table until all fins from this
                orientation are covered.

        ii. Extend line onto bulk of detector as shown in drawings.

        iii. Rotate frame so short edge with detector active area is
             against table and repeat.

    c.  Repeat for other side of frame.

    d.  Decide if you are doing a U or V frame. Take blue tape and
        attach to thin layer separating primed and unprimed planes in
        the edge view with excess tape towards primed side.

        i.  Run edge of screwdriver against tape and detector to ensure
            good adhesion.

        ii. Cut tape vertically along leading edge and fold tape over
            the primed fins.

    e.  Take double sided tape and tape detector onto table in
        orientation for U or V shown in picture.

        i.  Surround table around detector with clear plastic or Mylar
            to catch dripping epoxy.

        ii. Place fiber support tray to the right of the detector about
            5 inches away.

            1.  Place cover over tray.

    f.  Create 20 labels (label them U1, U2, U3 ... etc. or V1, V2, V3
        ... etc.) with enough spare so that they can be folded in half
        and taped around four fibers.

3.  Take four fibers from tray.

    a.  Align splice points using OptiVisor

    b.  Take small piece of blue tape. Attach across the four fibers on
        the wave-guide side of the splice and fold tape over itself.
        Tape should only be attached to one side of the fibers.

    c.  Take appropriate paper label and fold over fibers. Use a small
        piece of Scotch tape and secure allowing label to move freely
        over fibers.

4.  Insert fiber bundle into fiber support tray.

    a.  Take fiber support cover and lift it up on its left edge and
        slide along fiber support tray to the right until it is no
        longer over any fibers. Set aside.

    b.  Hold onto paper label and insert wave-guide part of fiber into
        its appropriate channel at far right side of tray while keeping
        the scintillating fiber out of the support tray.

    c.  Pull fiber through the tray until there is room to place cover
        on tray. Continue pulling until label is over the left edge of
        tray. While pulling, slide the cover after to keep all fibers in
        their appropriate channels.

5.  Insert scintillating fiber into frame.

    a.  With the splice point between the frame and the tray, gently
        ease the scintillating fibers into the frame until flush with
        top of fins.

6.  Pull fibers with blue tape until splice point is properly aligned.

    a.  To properly align splice point consider a line connecting the
        low edge of the graphite-covered part of the fins for the
        channel in question. Make the centerline of the fiber where it
        intersects the splice points coincide with the graphite line
        while looking through the OptiVisor.

7.  Gently push down on fibers near splice point on wave-guide side
    until fibers are flush with fins.

8.  Apply small drop of superglue near splice point and continue pushing
    down until glue cures.

9.  Repeat from step (3) until frame is filled.

10. Look at instructions for epoxying fibers.

11. After epoxy cures, remove blue tape from fibers and blue tape from
    frame.

12. Turn frame over and tape to table in the primed orientation as shown
    in drawing.

13. Place fiber-holding tray over the already filled fibers and slide
    the paper labels down towards the tray.

14. Create the appropriate primed paper labels (U'1, U'2, U'3 ... etc.
    or V'1, V'2, V'3 ... etc.)

15. Repeat from step (3) to step (10)

16. After primed side is cured, remove blue tape from frames and wrap a
    piece of tape around the end of the wave-guide part of the fibers
    keeping the primed and unprimed fibers separated.

17. Set detector aside until the cookies can be filled.

# X Frame Preparation

1.  Choose a good frame.

    a.  Look at channels 1 and 16 from an edge view and ensure that they
        do not narrow near the bottom. Look at the same channels from an
        overhead view. Look for warping. Slide a fiber through these
        channels and look for warping. If any of these things are
        observed, set frame aside and choose another.

2.  Prepare New Frame.

    a.  Take frame, aluminum mask and 0.5mm mechanical pencil to marble
        table.

    b.  Place edge of detector active area (gray area on picture)
        against table and gently push mask against detector.

        i.  Gently place graphite from pencil on exposed fins.

    c.  Repeat for X' side.

        i.  Draw line along edge of mask along bulk of frame on side
            with screw hole as shown in drawing.

    d.  Take blue tape and attach to thin layer separating primed and
        unprimed planes in the edge view with excess tape towards primed
        side.

        i.  Run edge of screwdriver against tape and detector to ensure
            good adhesion.

    e.  Place an old cookie-securing mask under the frame on the table
        away from you.

    f.  Take double sided tape and tape detector onto table in
        orientation for X shown in picture.

        i.  Surround table around detector with clear plastic or Mylar
            to catch dripping epoxy.

        ii. Place fiber support tray to the right of the detector about
            5 inches away.

            1.  Place cover over tray.

    g.  Create 16 labels (label them X1, X2, X3 ... etc.) with enough
        spare so that they can be folded in half and taped around four
        fibers.

3.  Take four fibers from tray.

    a.  Align splice points using OptiVisor

    b.  Take small piece of blue tape. Attach across the four fibers on
        the wave-guide side of the splice and fold tape over itself.
        Tape should only be attached to one side of the fibers.

    c.  Take appropriate paper label and fold over fibers. Use a small
        piece of Scotch tape and secure allowing label to move freely
        over fibers.

4.  Insert fiber bundle into fiber support tray.

    a.  Take fiber support cover and lift it up on its left edge and
        slide along fiber support tray to the right until it is no
        longer over any fibers. Set aside.

    b.  Hold onto paper label and insert wave-guide part of fiber into
        its appropriate channel at far right side of tray while keeping
        the scintillating fiber out of the support tray.

    c.  Pull fiber through the tray until there is room to place cover
        on tray. Continue pulling until label is over the left edge of
        tray. While pulling, slide the cover after to keep all fibers in
        their appropriate channels.

5.  Insert scintillating fiber into frame.

    a.  With the splice point between the frame and the tray, gently
        ease the scintillating fibers into the frame until flush with
        top of fins.

6.  Pull fibers with blue tape until splice point is properly aligned.

    a.  To properly align splice point consider a line connecting the
        low edge of the graphite-covered part of the fins for the
        channel in question. Make the centerline of the fiber where it
        intersects the splice points coincide with the graphite line
        while looking through the OptiVisor.

7.  Gently push down on fibers near splice point on wave-guide side
    until fibers are flush with fins.

8.  Apply small drop of superglue near splice point and continue pushing
    down until glue cures.

    a.  For X', fill channels 16 and 15 before using glue then proceed
        as normal

9.  Repeat from step (3) until frame is filled.

    a.  For X', allow superglue to cure hard in all channel then remove
        blue tape from fibers.

10. Look at instructions for epoxying fibers.

11. After epoxy cures, remove blue tape from fibers and blue tape from
    frame.

12. Turn frame over support with cookie-securing mask and tape to table
    in the primed orientation as shown in drawing.

13. Place fiber-holding tray over the already filled fibers and slide
    the paper labels down towards the tray.

14. Create the appropriate primed paper labels (X'1, X'2, X'3 ... etc.)

15. Repeat from step (3) to step (10)

16. After primed side is cured wrap a piece of tape around the end of
    the wave-guide part of the fibers keeping the primed and unprimed
    fibers separated.

17. Set detector aside until the cookies can be filled.

## Epoxy Preparation

1.  Take a plastic beaker, bottle of hardener, can of resin and a spoon
    to digital scale.

2.  Place beaker on scale and tare.

3.  Add 2.5 g of resin to beaker.

4.  Add 0.7 g of hardener to beaker (total to 3.2 g)

5.  These amounts are sufficient for one frame. Increase in weight
    proportion for more.

6.  Return supplies to clean room.

7.  Take beaker and turn spout down until beaker is oriented at about 45
    degrees to the vertical.

8.  Scrape resin from the bottom of the beaker into the pool of hardener
    with the tip of a syringe.

9.  Thoroughly mix hardener and resin.

10. Allow epoxy to sit for about 10 minutes after mixing to begin to
    set.

## Frame Gluing

11. Pour small amount of epoxy over middle of active area and push to
    cover all the fibers in the frame that are within the fins. Do not
    put any epoxy outside of the fins.

12. Gently wiggle each scintillating fiber in the channels to encourage
    epoxy to filter down into frame.

13. Place a small amount of epoxy over scintillating fibers that are
    outside of the frame. Spread out over all the fibers and gently
    wiggle fibers to encourage epoxy to fill in around the fibers.

14. Allow epoxy to seep into the fibers for about 15 to 20 minutes.

15. Repeat the above procedure from step (11) using slightly less epoxy.

    a.  For X' Frame:

        i.  Get a Trigger Scintillator

        ii. Place some epoxy on the edges of the channel.

        iii. Insert the Trigger Scintillator into the channel and align
             the pencil mark on the frame with the joint between the
             scintillating trigger and the wave-guide.

        iv. Push the trigger flush with the frame.

        v.  If there are any gaps between the trigger and the frame, put
            a small amount of epoxy and allow to seep down.

    b.  Take flat sheet of plastic covered in Mylar and place edge of
        wave-guide fibers and lower over the epoxy.

    c.  Push down onto frame and place a 100g weight over the plastic.

16. Allow epoxy to cure overnight for \~24 Hrs.

17. Gently remove weight and sheet of Mylar covered plastic.
