The JWST Time-Domain Field is one of the future Guaranteed Time Observations (GTO) program fields of James Webb Space Telescope(JWST), surveying about 14’ diameter field at the North Ecliptic Pole (NEP) with NIRCam/NIRISS and will be the best field to study extragalactic deep science. JWST-TDF SCUBA-2 submm survey aims to extend the sub-mm data coverage of this field which is powerful to study high-z star forming histories and to find new submm galaxies in this field. Submm galaxies(SMGs), the main target of this study, are expected to be highly star-forming (SFR>400Msol/yr) galaxies holding the hints to reveal the mystery of star formation history in high redshift. In this study, we detect 93 submm sources at S/N > 3.5 and the rms error reaches 0.9mJy/beam in the manner of depth. With VLA 3GHz radio catalog, we identified that 68 submm sources have radio counterparts. In this talk, we will introduce the SCUBA-2 JWST NEP Time-Domain Field project and the newly discovered sub-mm sources in this field.
