A new haloscope for Axion dark-matter search is under study using in a first step the large bore superconducting magnet in construction at the LNCMI in Grenoble, which will produce 9~T in 812~mm diameter and 1400~mm height. Microwave cavities of high quality factor $Q\sim10^5-10^6$ will be developed at CAPP/IBS in Daejeon. Low-noise microwave amplification of the signal will be ensured by DC superconducting quantum interference devices (SQUID) or/and Josephson parametric amplifiers (JPA) cooled-down to 20~mK by a $^3$He/$^4$He dilution refrigerator. This new haloscope will be designed to probe QCD dark-matter Axions in the mass range of 1-100~$\mu$eV with unprecedented sensitivity.
