  We investigate the effect of interactions on Andreev current at a
normal-superconducting junction when the normal phase is a Luttinger liquid
with repulsive interactions. In particular, we study the system of a finite
sized carbon nanotube placed between one metallic and one superconducting lead.
We show that interactions and finite size effects give rise to significant
deviations from the standard picture of Andreev current at a normal-
superconductor junction in the nearly perfect Andreev limit.
