I have witnessed that phenomena with my 6"x19 5kVDC excited coil 8x20"
torus, .1uF vacuum switch (Pin=.4W 9v 40ma) 1 to 2 discharges/s.
I believe was seeing the E-Field shaped in blue corona as a result of ionizing
the nitrogen when the energy was high enough in the sshot mode in the non
break out mode - smoothe torus surface - such that eye sensivity is maximized
in total darkness. Study of the corona/field reveals where spark channels were
likely to form more dense events (a whispy air discharge or as a ground plane
approaches a bright power discharge). In the absense of a close plane
influence to the top, the ability to physical view of the nature/shape of the
E-Field, most prominent at the top but also encomapassing the upper
secondary is informative as to pri/sec position, tuning, coupling, Ctop shape
and position, etc.
Looking forward to more "visions" and relevance to field study & influence.
