To further the capability with Direct Wind technology, ongoing tests are
being used to develop and determine the range of the process. Figure 25
shows the result of refinements to the wiring process. On the left is a
sextupole coil wound around a 1 inch diameter support tube. It has five
turns in serpentine fashion, this results in a 2.5 turn per pole magnet.
On the right is a 6 turn serpentine sextupole. Note that the inner radius,
therefore the pole angle, has been reduced, and each pole now has 3 turns
equivalent.

Ongoing work will be towards tighter bend radii, as well as reduction of
the support tube diameter.
