I have to measure ion speed (to be used in direct electricity generation using MHD). I install the probe very close to the plasma ball, the problem is at the end when the plasma ball generates an explosion burning any carbon based coating and breaking any ceramic material nearby.
Actually the Rogowski coil is a copper wire coated by a thin PTFE coating.
What electric isolation would be recommended?
If possible use the magnetic field near
a metal surface to insulate the coil from
electrons. Ion flow and radiation will destroy
the coil during the pulse.
That is true, but I would like measure particle flux in the inner area and the magnetic field would act as a mirror
It is right but in such heavy duty place I used needle sensors. I have submited following article:
Z-PINCH HIGH POWER NEEDLE FILTER
Unfortunately I obtain light/no light, no photos of every particle
Here is a photo of the environment, where some megawatts of light are released
