The Iranian Light Source Facility (ILSF) is a new 3 GeV third generation synchrotron light source which is consisted of several pre-accelerators and a storage ring with the beam current of 400 mA. Based on the main lattice candidate, the storage ring includes of 100 dipoles, 320 quadrupoles and 320 sextupole magnets. To develop fabrication procedures and techniques and to compare the measuremen...

  In the light of environmental graphics consists of two source of natural light and artificial light .The natural light is provided  by the sun . An unpredictable thing that can not be easily controlled, and we are bound to build our environment around it .Artificial light is taken from the technology response in line with the human need to turn their world after dark. Artificial light can be...

The Iranian Light Source Facility (ILSF) as a national project is a 3 GeV third generation synchrotron light source facility which provides high energy super bright X-ray for the users. Design of the ILSF storage ring emphasizes an ultra low electron beam emittance (below than 5 nm.rad), beam current of 400 mA, great brightness, stability and reliability which make it competitive in the operati...

introduction blue light is a part of the spectrum with the highest energy content, which can reach the retina. the damage that it can cause to the retina is called photochemical or blue-light retinal injury. for the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (w.m-2.sr-1) seems to be ...
