Faraday Cage TEST

Tests on the Faraday-Cage are addressed to determine:

  • Electronic noise
  • Dynamic range
  • Transfer Function

The tests were performed varying two parameters:

  • the equivalent electric circuit which represents the plasma coupling impedance
  • the bias current

Only a representative subset of conditions has been chosen for each test. The value of the plasma impedance was established for three different combinations of plasma densities and temperatures. The plasma coupling parameters adopted for measurements are shown in the following table.
