| Summary:
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.
