The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a Radio Telescope in British Columbia 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.
