Updates on NEW-MUSIC: The Next-generation Extended-Wavelength Multiband Sub/millimeter Inductance Camera
Simon Hempel-Costello, Graduate Student, The Division of Physics, Mathematics and Astronomy, Caltech,

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.

This talk will serve as my practice candidacy defense, in which I will contextualize and develop the design and underlying physics of the NEW-MUSIC instrument. I will further discuss my ongoing work on low-frequency noise measurement and characterization of the amorphous silicon parallel-plate capacitors used by NEW-MUSIC, as well as my work on stacking and dust/gas mass analysis of the CHAMPS survey, a 1.2 mm ALMA survey overlapping the COSMOS field.
