We consider a non-commutative U(1) gauge theory with an extension which was originally proposed by A. A. Slavnov in order to get rid of UV/IR mixing problems. Here we show, that the improved IR behaviour of this model is mainly due to the appearence of a linear vector supersymmetry.9 pages, work presented by D. N.
