Hello everyone,
My name is Fred and I'm a newcomer to the forum. I'm designing a very simple E-field sensor. So all I did was I got two styrofoam balls, wrapped them around with a few layers of aluminum foil to serve as charge collecting surfaces. Put both "sensors" on the ends of a thin wood rod about 1m long. Hooked it up to my oscope and measured nothing. Expected, since the potential should be very small anyways. So I connected a 100GOhm resistor in series and then connected to the oscilloscope. Now I should be reading a decent (and somewhat steady) potential.
But that's not happening. Any suggestions or comments?
Thanks a lot,
Fred
