Abstract
The non-semisimple current superalgebra in the standard basis and the corresponding non-unitary conformal field theory are investigated. Infinite families of primary fields corresponding to all finite-dimensional irreducible typical and atypical representations of and three (two even and one odd) screening currents of the first kind are constructed explicitly in terms of ten free fields.
