towards the other.
incorporated by reference.
Tube 54 is preferably about 5 cin (2") from the area in which an active sterile field
is desired and operates at about 60 KeV. Higher voltages may allow a greater gap, and a
lower voltage might require a lesser gap. FIGURE 3A shows the pre-sterilized components
10, 12 arranged prior to connection. Tube 54 creates the spherical-shaped e-bearn field 60
having approximately a two-inch diameter. Other diameters of the sterile field are certainly
possible, however manipulation of the joining of components requires very little space.
Where a greater space is required, field 60 could be made larger by conventional methods.
Referring to FIGURE 3B, the ends 14 of components 10, 12 are conveyed into the
sterile e-beam field 60. While maintained within sphere 60, ends 14 of each component 10,
12 may be cut-off, as shown in FIGURE 3C, to create opened ends. The mechanism for
opening these ends may be a mechanical blade, which may be held permanently within the
e-beam field 60 to maintain its sterility, or any other suitable cutting or opening mechanism.
FIGURE 3D shows that once the ends 14 are cut-off, the resulting open ends are connected
together while still within the field 60.
