### Description

$J/\psi$ production is considered as one of the very important probes for studying the properties of quark-gluon plasma (QGP). PHENIX observed a large suppression of $J/\psi$ production in Au+Au collisions at $\sqrt{s_{NN}}=$ 200 GeV in comparison with binary collision scaled p+p collisions. The level of this suppression is similar to that observed in other energies in CERN-SPS and LHC. PHENIX also took $J/\psi$ data from Au+Au collisions at $\sqrt{s_{NN}}=$ 39 and 62 GeV in 2010. This data allow us to explore the energy dependent suppression level in order to disentangle the important contributing factors of $J/\psi$ production. We will present the $j/\psi$ $R_{AA}$ results at 39, 62.4 GeV in comparison with our previously published 200 GeV results.
