tokens: If a low energy plasma ( temperature of the order of 1 electron volt or less ) is used to initiate the electrostatic discharge the inverted voltage gradient is obtained using plasma instead of vacuum in the chamber and the tests shall be modified as follows : 1 . Modify the absolute capacitances representing the satellite capacitance and solar array capacitance in order to keep the same energy for the primary discharge , since the discharge voltage is lower . 2 . Verify that the plasma path impedance does not prevent all the available charge to be discharged .
