The Tomographic Ionized-carbon Experiment (TIME) is a spectrometer in development for intensity mapping of the ionized carbon forbidden line [CII] (158 μm) from the epoch of reionization, to be used as an indication of star formation. The resulting wavelength corresponds to the redshifted carbon monoxide spectral lines from later periods, e.g., peak star formation, requiring analysis to distinguish which is which. TIME is independent of 21-cm experiments, and offers the opportunity to correlate results.
An initial version of the TIME spectrometer (which was, for a while, termed TIME-PILOT), which doesn't yet support its eventual field of view, has been under development. Currently, the future completed version is termed TIME-NG. Various telescopes have been considered, including the James Clerk Maxwell Telescope, but current plans are to install the initial version for a run on the ARO 12m Telescope, then for a subsequent run (termed TIME-EXT) on the Caltech Submillimeter Observatory (CSO), which is being re-installed at the Llano de Chajnantor Observatory, as the Leighton Chajnantor Telescope (LCT).
