The rotary gap system has now been dynamically balanced
using two accelerometers and a phase-locked strobe light,
and the unbalanced forces are now under 20lb (not bad for
a rotating system with 2000G's at the edge).
Beforehand, the gap would excite several mechanical
resonances, including a rather unpleasant one in the
walls the vault structure around 1900 RPM!
The last couple of weeks have been filled with getting
various permits and blessings, troubleshooting the SCR
control circuitry, and dodging the weather...
We are just about ready for the initial single-shot
tests at this point, and the goal is to have some sparks
on New Years' Eve. Then we plan to regularly operate
the coil thru Jan 13, and teardown on the 14th.
