摘要：
安装在Leighton Chajnantor望远镜（LCT）上的下一代扩展波长多波段亚/毫米电感相机（NEW-MUSIC）将是首款六波段跨毫米波（"trans-mm"）偏振计，覆盖2.4倍频程的光谱带宽，为跨毫米波时域前沿开辟新窗口，尤其是在能量、密度、时间和磁场领域的新前沿。NEW-MUSIC的宽光谱覆盖还将支持利用Sunyaev-Zeldovich效应研究星系和星系团热气体晕中的吸积、反馈和尘埃含量。带有偏振信息的六波段光谱能量分布将为恒星和行星形成区研究带来新见解。NEW-MUSIC将采用偏振敏感超导缝隙偶极子天线的分级相控阵，搭配光刻带通滤波器，在LCT的14角分视场内以80-420 GHz的六个光谱波段（1:5.25的光谱动态范围；2.4倍频程）实现近乎最优的阵列填充。光将被传输至铝或铝锰微带线耦合的平行板电容集总元动能电感探测器（MS-PPC-LEKIDs），这是一种全新的KID架构，在提供背景限制性能的同时大幅提升了设计灵活性。创新的宽带宽刻蚀硅结构将用于背照式焦平面的抗反射处理。NEW-MUSIC将以高成本效益的方式复用MUSIC仪器的大部分组件，初期部署四分之一规模焦平面即可开展大部分NEW-MUSIC科学研究，后续再部署全视场焦平面以满足NEW-MUSIC广域巡天科学的需求。
英文摘要：
The Next-generation Extended Wavelength-MUltiband Sub/millimeter Inductance Camera (NEW-MUSIC) on the Leighton Chajnantor Telescope (LCT) will be a first-of-its-kind, six-band, transmillimeter-wave ("trans-mm") polarimeter covering 2.4 octaves of spectral bandwidth to open a new window on the trans-mm time-domain frontier, in particular new frontiers in energy, density, time, and magnetic field. NEW-MUSIC's broad spectral coverage will also enable the use of the Sunyaev-Zeldovich effects to study accretion, feedback, and dust content in the hot gaseous haloes of galaxies and galaxy clusters. Six-band spectral energy distributions, with polarization information, will yield new insights into stellar and planetary nurseries. NEW-MUSIC will employ hierarchical, phased arrays of polarization-sensitive superconducting slot-dipole antennas, coupled to photolithographic bandpass filters, to nearly optimally populate LCT's 14' field-of-view with six spectral bands over 80-420 GHz (1:5.25 spectral dynamic range; 2.4 octaves). Light will be routed to Al or AlMn microstripline-coupled, parallel-plate capacitor, lumped-element kinetic inductance detectors (MS-PPC-LEKIDs), an entirely new KID architecture that substantially enhances design flexibility while providing background-limited performance. Innovative, wide-bandwidth, etched silicon structures will be used to antireflection-treat the back-illuminated focal plane. NEW-MUSIC will cost-effectively reuse much of the MUSIC instrument, initially deploying a quarter-scale focal plane capable of the bulk of NEW-MUSIC science followed later by a full-FoV focal plane needed for NEW-MUSIC wide-area survey science.
