Abstract : A mass spectrometer system has been purchased by this grant. The purchased equipment were used to construct an apparatus as shown in Fig. 1. This apparatus includes a quadrupole mass analyzer, ion detectors, high vacuum pump system, a vacuum chamber, electronics and power supplies, as well as optical multichannel analyzer and excimer laser. This apparatus is being used to analyze the positive and negative ions produced in electrical discharges. The transient chemical species in electrical discharges (such as radicals and excited ions) are also being investigated using this apparatus. The information obtained from this research are useful for the understanding of discharge mechanisms. Keywords: Electron production, Electron attachment, Charge recombination.
