In the first phase of Delhi Light Source (DLS) project, a photocathode based normal conducting RF gun will be used to produce electron beam of energy ∼ 8 MeV. The short pulses from a high power laser system will be split in to many pulses ('Comb beam') and will be used to produce electron beam bunches which will be injected in to a compact, variable gap undulator magnet to produce THz radiation. Different components of the facility e.g. the copper cavity, photocathode deposition setup, high power RF system, laser device, Undulator magnet etc. are being designed, developed or procured. It is expected that the production of electron beam and THz radiation will be demostrated by end of 2017 and 2018 respectively. Copyright © 2016 CC-BY-3.0 and by the respective authors.
