Indus-1
Indus-1 is a 450 MeV electron storage ring which emit synchrotron radiation from
it's four bending magnets. Several experiments can be performed concurrently on
such a synchrotron facility by the use of the so-called 'beamlines'. The main
characteristics of the various beamlines that are set up/ being set up on
Indus-1 are given in the following pages to enable potential users of this
facility to plan their experiments. Main parameters of Indus-1 storage ring are
also given. Beamlines and the experimental stations may be upgraded in future
depending upon the experimental requirements.
Indus-1 was declared as
commissioned in the middle of the year 1999. The stored electron beam current of
161 mA has been already achieved as against the design value of 100 mA. The beam
life time is around one hour at 100 mA beam current. The life time is expected
to improve in the next phase of Indus-1 operation.
