SUMMARY:A novel on-chip\, mm-wavelength spectrometer for mapping the h
igh-redshift universe.\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, E

DESCRIPTION:Title: A novel on-chip\, mm-wavelength spectrometer for ma
pping the high-redshift universe.
\n
\nSuperSpec is an compact
on-chip spectrometer for mm and submm wavelength astronomy. Its small
size\, wide spectral bandwidth\, and highly multiplexed detector read
out will enable construction of powerful multi-object spectrometers fo
r high-redshift observations. The design employs a filter bank consist
ing of a series of superconducting thin film circuit elements\, each c
oupled to titanium nitride lumped-element kinetic inductance detector
(KID.) I will discuss the design\, optimization\, and measured perfor
mance of our prototype devices\, our upcoming observing run with the S
uperSpec demonstration camera\, and the observations that will become
possible with a large multi-object-spectrometer based upon this techno
logy. These future instruments will allow us to characterize thousands
of high redshift dusty star forming galaxies and to measure to charac
terize star formation during the epoch of reionization through tomogra
phic intensity mapping.
