Description

Line Intensity Mapping (LIM) is an emerging cosmological survey technique that measures the integrated emission of certain atomic and molecular lines with high throughput and low spatial and spectral resolution to quickly map large volumes of the large scale structure distribution in our universe. Mm-wave LIM would measure the redshifted emission from CO/[CII] using established survey techniques developed by CMB experiments. This presentation will discuss progress of a mm-wave LIM detector development program focused on Microwave Kinetic Inductance Detector (MKID) arrays with on-chip filter banks and feedhorn-based optical coupling. It will describe the cosmological goals of LIM at mm-wavelengths and the staged R&D approach, and will discuss the current status of technology development where a small array, called the SPT Summertime Line Intensity Mapper (SLIM), will be deployed for summer observations on the South Pole Telescope.
