CHIME, one of the largest radio telescopes in the world, is under construction at the Dominion Radio Astrophysical Observatory in Canada. CHIME combines a stationary telescope with a massive signal-processing computer to generate one thousand beams on the sky. CHIME was designed primarily as a cosmology experiment, aimed at measuring the distribution of red-shifted atomic hydrogen in the range 0.8 < z < 2.5, www.ts-watches.me corresponding to the frequency range 400 to 800 MHz. This is the epoch where Dark Energy becomes a significant factor in the expansion of the Universe. With its very large sky coverage CHIME is also an ideal telescope for the study of the transient sky, and the telescope is being equipped to search the cosmology signal stream for Fast Radio Bursts. It will also be a powerful tool for pulsar research.

This talk will describe the motivation behind the project, the design and construction of the telescope, and its potential use to study the Interstellar Medium of the Milky Way.
