The property of the conformal algebra to contain the Schr\"odinger algebra in
one less space dimension is extended to the supersymmetric case. More
precisely, we determine the counterpart of any field theory admissible super
conformal algebra. Even if each type of superalgebra provides a different
solution, its basis decomposition into two copies of the super Schr\"odinger
algebra, differing only by their super Heisenberg part, remains valid in all
the cases, so generalizing a feature already observed in the non supersymmetric
conformal case.Comment: 30 page
