PS Stefan's coil is very compact. 0,4 mm wire? Hope it can take the kV!
Hi Joe,
Yes, 0.4mm wire. The voltage is not the problem for the wire. But the
tube is out of PVC and the length of the winding is about 0.3m. So it
will be about 1kV/cm which could be problematic if the inner side of the
tube becomes wet, inhomogeneous wet. This could cause strong local E
field strength which leads to arcing on the surface. Arcing on the
surface makes the surface conductive, a self accelerating process that
can be repaired. This is the high risk of this construction! It has its
advantages and disadvantages. It will handle 700 mA RF current, at least
now in winter :-) But i should take care to keep it as dry as possible.
We will see what happens.
73, Stefan
