Description
At the Iranian Light Source Facility (ILSF), two different storage ring options are being studied. The designs differ in emittance. In the first option the calculated emittance is $3.278 nm-rad$ whereas for the second option emittance is $0.937 nm-rad$. In this paper the electron beam emittance effects on the source radiation properties from bending magnet, wiggler and undulator, X-ray optics and the beamline design are carefully studied. The present calculations demonstrate that in the case of $0.937 nm-rad$ brilliance of undulator is increased by a factor of about 5. For bending magnet, flux is reduced almost 1 order of magnitude for hard x-ray regime. Because of smaller size of the source for undulator at the case of $0.937 nm-rad$, we can achieve to a smaller spot size and higher resolution with easier focusing systems and usual kind of monochromator than the emittance of $3.278 nm-rad$ and for the bending magnet hard x-ray beamline, size of the mirrors reduced $30%$ in the $0.937 nm-rad$ emittance case, so its result is shorter mirror, low cost and perhaps more challengeable heat load.
