Abstract

The use of high-pressure microdischarges formed in metal capillary tubes to study excimer emissions was discussed. It was found that excimer emission intensity increases with argon flow rate, ambient pressure and discharge current. The current voltage dependence indicated operations in the abnormal glow discharge mode. It was also found that a source of intense excimer radiation could be fabricated by simultaneously operating dual microdischarges such that the intensity of a single discharge is maximum.
