The experimental set-up and the ionizer. a The configuration and size of the test chamber and the locations of the ionizer and fan. The ionizer is located 30 cm from the bottom of the box, and the fan is located 7 cm from the top. b The ionizer has three components: high voltage generator (power pack), ground electrode and discharge electrode. It is characterized by a specific frequency and an alternate D.C. pulse-high positive/negative voltage. The input voltage of the power pack is 12 V in D.C., and the output voltage is peak-to-peak ± 2.8 kV
