The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a Radio Telescope in British Columbia, Canada to map the distribution of neutral Hydrogen in the Redshift range of .8 to 2.5 (Hydrogen Intensity Mapping). It consists of four cylindrical reflectors in a static configuration, i.e., a Cylindrical Telescope. It views half the sky by sweeping out a longitudinal arc over the course of the Earth's rotation. It aims to observe the redshifted 21cm Line redshifted to its Frequency range of 400MHz to 810MHz.
