Unfortunately, I cannot post any data, but the noise consists of a burst of spikes going from around -2 to +2 millivolts with a rise and fall of roughly a couple of ns. It lasts a couple of hundred ns in total.
What is the bandwidth of the signal that you want to separate from the noise? What is the source impedance of the ion current source detector? Why do you show a series 50 Ohm resistor in each piece of coax in your model?
