THOR coupling coeff. measurement results

["Marco Denicolai" <Marco.Denicolai-at-tellabs.fi> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Hello all.

I have been measuring the coupling coeff. vs. primary height in the Thor
TC. For
those of you interested in the results, here they are.

Height            k
 (mm)
149  0.224875339
132  0.218668702
92   0.203950105
51   0.18728085
10   0.169370268
-30  0.150041026
-69  0.131953111
-109 0.117766511
-129 0.107126561

Height is measured from the primary turns to the lower secondary turn (as
usual). Primary is flat and features 9 turns of copper pipe, which were all
used
during the measurement.
