Description
In this talk, we present the current status of the
observation planning for the CCAT (Cerro Chajnantor Atacama Telescope)
EoR-Spec (Epoch of Reionization Spectrometer). EoR-Spec is one of the
Prime-Cam modules of Fred Young Submillimeter Telescope (FYST)
operated by the CCAT Observatory. It covers the frequency range
between 210 to 420 GHz and uses a cryogenic scanning Fabry-Perot
Interferometer with a resolving power of ~100 as its spectral
device. EoR-Spec will be installed in Prime-Cam during the second year
of CCAT operation. The primary science goal of the EoR-Spec is the
investigation of the evolution of the ionizing sources during and post
EoR. This is accomplished by a deep spectroscopic survey (DSS) of the
E-COSMOS and E-CDFS fields in [CII] via the line intensity mapping
method, covering the redshift between 3.5 to 8. We performed coverage
simulation of DSS with various scanning patterns and parameters and
investigated the mapping efficiency and homogeneity. We will also
present the calibration strategy, as well as plans for commissioning
and the early science phase.
