Since its inception in 2010, the ILSF project has grown into a large project employing more than 100 engineers and physicists of diverse backgrounds and expertise in its various departments. The project is now entering its detailed design phase: after the completion of the conceptual design report further work was carried out on various designs of the storage ring lattice, and it was decided that a larger ring with a circumference of about 500 meters and weaker fields would provide several advantages including a lower emittance and more straight sections, as well as wider options for the construction of the storage ring magnets.
In the meantime, prototypes have been constructed for the RF cavity, solid-state RF amplifiers, low-level RF control systems, an H-type dipole magnet, highly-stable magnet power supplies, storage ring quadrupole magnets, girders for sextupole, quadrupole, and dipole magnets, linac quadrupole, various types of vacuum chamber. Work has been also carried out on the design of an RF electron gun with a thermionic cathode, and an alpha-magnet for longitudinal compression of electron bunches; simulations show that this electron gun provides a much better beam quality compared with conventional DC electron guns. The prototype of the RF electron gun has been constructed and low-power RF measurements as well as machining and roughness measurements show promising results.
The site chosen for the building of ILSF synchrotron is in the lands donated by Imam Khomeini International University in Qazvin. Upon the final approval of the design work will start on the detailed design of the synchrotron and other facilities.
The storage ring has the following characteristics:
Beam Energy: 3 GeV
Beam Emittance: 0.937 nm.rad
Circumference: 489.6 m
Number of straight sections: 28
Number of superperiods: 14
