A modular system for constructing an atmospheric pressure plasma source. A plasma torch module may be constructed by reassembling the structural components of two (2) different models of spark plugs. Each module can produce a plasma torch having a radius of about 1 cm or more, a height of about 6 cm, and a peak density exceeding 10.sup.13 cm.sup.-3. A set of modules, each connected in series, may be used with a ballasting capacitor such that an array can be operated while sharing a common power …
