VPI Trials
Attached are two new sets of photo's taken from last weeks VPI using
the 4-conductor rope. Once again it clearly shows good fill between the
copper stands. This VPI was performed at a slightly higher temperature as
recommended by CTD. One of the photo's is at 88,000 X magnification.
We will continue to take sample photo's of different VPI injections to
ensure that this wetting between stands is always reproducible.
Test Specimens
Monday another set of specimens were VPI'd for the CTD epoxy
tests. We will VPI another set on Thursday then again early next
week. This process will continue until all of the specimens have been
completed.
Keystone
A controlled bench top test is being performed on Keystone measurements.
This will provide preliminary data using the 4-conductor prior to completing
the windings on the Keystone fixture. Steve will take Faro
measurements on the fixture this afternoon. We've had some difficulty
with the glass tape being used on the taping machine. The ends of the
glass are not stitched causing some wrinkling. New glass should be here
by Monday.
Demo coil
Machining of the lead outs on the racetrack demo coil form is nearly
complete. Work is continuing on the fabrication of the winding
clamps. These clamps will be used for the winding the demo coil
(racetrack).
Tooling
The autoclave drawings are ready to be moved up to FDR status. Only
the final specifications for the autoclave are keeping us from holding a FDR.
The drawings of the coil turning fixtures are nearly complete.
