格勒诺布尔LNCMI正在研制一种用于轴子暗物质研究的新型晕圈镜，初步使用的是正在建造的大口径超导磁体，它将产生直径812 mm、高度1400 mm的9 T。位于大田的CAPP/IBS将开发高品质因数的微波谐振腔。信号的低噪声微波放大将由直流超导量子干涉器件（SQUID）或/和约瑟夫森参量放大器（JPA）保证，该放大器由$^3$He/$^4$He稀释制冷机冷却到20 mK。这种新的晕圈镜将以前所未有的灵敏度探测质量范围为1-100 μ $eV的QCD暗物质轴子。
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 $Qsim10^5-10^6$ 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.
