The de­mand for a light source with high bright­ness and short pulse length from the re­searchers in the field of phys­i­cal, chem­i­cal, bi­o­log­i­cal and med­ical sci­ences is grow­ing in India. To cater to the ex­per­i­men­tal needs of mul­ti­dis­ci­pli­nary sci­ences, a pro­ject to de­velop a com­pact Light Source at Inter Uni­ver­sity Ac­cel­er­a­tor Cen­tre (IUAC) has been taken up. In the first phase of the pro­ject, pre­bunched [1] elec­tron beam of ~ 8 MeV will be pro­duced by a pho­to­cath­ode RF gun and co­her­ent THz ra­di­a­tion will be pro­duced by a short un­du­la­tor mag­net. In the sec­ond phase, the en­ergy of the elec­tron beam will be in­creased up to 50 MeV by two sets of su­per­con­duct­ing nio­bium res­onators. The co­her­ent IR ra­di­a­tion will be pro­duced by using an un­du­la­tor mag­net (con­ven­tional method) and X-rays by In­verse Comp­ton Scat­ter­ing. To in­crease the av­er­age bright­ness of the elec­tro­mag­netic ra­di­a­tion, fab­ri­ca­tion of su­per­con­duct­ing RF gun is going to be started in a par­al­lel de­vel­op­ment. In this paper the de­tailed de­sign of the LSI ac­cel­er­a­tor com­plex as well as con­struc­tion timetable will be pre­sented. The phys­i­cal prin­ci­ples of THz gen­er­a­tion and major ac­cel­er­a­tor sub­sys­tems will be dis­cussed.
