“…This results in a closed-orbit displacement of the stored electron beam over the entire ring. In addition, if the electron beam is placed somewhere off-center in the insertion device, the integrated-quadrupole error looks like a dipole and steers the beam [6][7][8]. This results in a closed-orbit distortion that can be larger than the acceptable limit.…”

Indus-2 is an Indian synchrotron light source, operating at 2.5 GeV and generating synchrotron radiation from its bending magnets. In order to provide more intense synchrotron radiation to the synchrotron users, there is a plan to install five insertion devices in the Indus-2 storage ring. In the first phase of installation of insertion devices, there is a proposal to install two out-vacuum pure permanent magnet linearly polarized undulators in long straight sections of the Indus-2 storage ring. The presence of the insertion devices in the ring has inevitable effects on beam parameters like betatron tune, betatron amplitude function, closed orbit, emittance, energy spread and dynamic aperture etc. In this paper, the effect of two undulators on the above mentioned parameters of the Indus-2 stored electron beam at 2.5 GeV is presented. Moreover a correction scheme for the restoration of the betatron tune and amplitude function is also presented.
