Hi Malcolm,

Here are ones to the side:

Here are ones "almost" vertical.  It seems to me that the orentation is
dependant on the coil set up and the helical arcs occur in both.

I suspect there are power and other variables that have to be within a
specif range for them to occur.  The first picture shows the arcs through
many stages of power density.  Powerful pulsed CW coils seem the best at
making them.

Cheers,

	Terry
