We report the multi-wavelength properties of millimeter galaxies hosting X-ray detected active galactic nuclei (AGNs) from ALMA Lensing Cluster Survey (ALCS). ALCS is an extensive survey well-studied lensing clusters with ALMA, covering area 133 arcmin$^2$ over 33 a 1.2 mm flux-density limit ${\sim}$60 $\mathrm{μJy}$ ($1σ$). Utilizing archival data Chandra, we identify three AGNs at $z=$1.06, 2.09, and 2.84 among 180 sources securely in (of which 155 are inside coverage Chandra). The spectral analysis shows that two not significantly absorbed ($\log N_{\mathrm{H}}/\mathrm{cm}^{-2} < 23$), while other signs moderate absorption N_{\mathrm{H}}/\mathrm{cm}^{-2}\sim 23.5$). also perform energy distribution (SED) modelling to photometry. find our AGN sample both high mass accretion rates (intrinsic 0.5--8 keV luminosities ${\sim}10^{\text{44--45}}\,\mathrm{erg\ s^{-1}}$) star-formation (${\gtrsim}100\,M_{\odot}\,\mathrm{yr}^{-1}$). This demonstrates wide-area Chandra can selectively detect intense growth supermassive black holes (SMBHs) high-redshift universe.
