Synchrotron Radiation Source: INDUS-1



INDUS-1, the first Synchrotron Radiation Source (SRS) of India is under regular operation now at the Centre for Advanced Technology (CAT), Indore. The stored current has reached twice the design value and the life time of the INDUS-1 beam is nearly one hour. This lifetime is limited by the pressure in the vacuum chamber which is of the order of 10-8 torr. With the operation of INDUS-1, it is expected that the vacuum will improve and a pressure 10-9 torr will be reached. At this pressure, the lifetime of its beam is expected to be a few hours.


INDUS-1 consists of an injector system a 20MeV microtron and 700MeV booster synchrotron and 450MeV storage ring. All the three accelerators and their subsystems have been indigenously designed and developed.


To utilize the radiation from INDUS-1, five beamlines have been planned. Of these, two are already installed and commissioned one each was designed, developed and constructed at CAT and the Inter-University Consortium for DAE Facilities (IUC-DAEF), Indore. The beam lines are now routinely used for research work.


INDUS-2 is the second electron storage ring under construction at CAT. It will have nominal operating electron energy of 2.5 GeV. Injector system, presently working for INDUS-1, will also provide accelerated electron beam of 700MeV to INDUS-2.
