We investigate transport in highly transparent single-wall carbon nanotube Josephson Junctions. Gate tunable supercurrent, multiple Andreev reflections and hysteresis current-voltage characteristics are observed, corresponding to on- and off-resonance transmission of charges via the nanotube's quantized energy levels. In the talk we will discuss the dependence of supercurrent on temperature, source-drain separation and gate voltage, and compare with various theoretical models.
