The discharge current is measured using a Bell-NT5 magneto-resistive sensor. This sensor is positioned in the electrical circuit between the anode and the discharge voltage generator (green circles in Fig. 2). The discharge current flows through the sensor, which returns a voltage proportional to the discharge current. This voltage is then acquired directly by a digital oscilloscope with an input impedance of 1 MΩ. The oscilloscope used throughout the study is an Agilent Infiniium MSO9254A.
