The effects of experimental parameters on the emission of Extreme Ultra Violet (EUV) from plasma produced by vacuum spark discharge using Tin as anode material were studied. The operating pressure for all the experiments carried out was maintained at below 10-4 mbar. The discharge voltage tested was from 10 kV to 25 kV. The inter-electrode distance suitable for high intensity and reproducible EUV emissions was obtained to be in the range of 3.6 mm to 5.6 mm. The output EUV energy was found to scale as ∼V02, where V0 is the discharge voltage.
