### Description

The detector of Jiangmen Underground Neutrino Observatory (JUNO) is the largest underground liquid scintillator detector in the world, and it is expected to start data-taking in 2023. The JUNO detector mainly consists of a 20 kton liquid scintillator and a large number of photomultiplier tubes. It will work as a multi-purpose detector, aiming to determine the neutrino mass ordering as its primary experimental goal by measuring the energy spectrum of reactor neutrinos, and to study atmospheric as well as astrophysical neutrinos, etc. A comprehensive calibration program has been developed to achieve an energy resolution of $3\%/\sqrt{E[{\rm MeV}]}$ and accuracy of better than 1% in the reactor neutrino energy range through understating the liquid scintillator non-linearity as well as detector non-uniform response. This poster will present the overall strategy of the JUNO detector calibration and its hardware systems that have been developed to make it possible to deploy a calibration source in various positions inside the detector.
