DELSY—Dubna ELectron SYnchrotron at JINR

The project DELSY is under development at JINR. It is based on an accelerator facility presented to JINR by the Institute for Nuclear and High Energy Physics (NIKHEF, Amsterdam): linear accelerator MEA and electron storage ring. Analysis has shown that it would be possible to build in Dubna a universal light source with unique characteristics consisting of the following components: a complex of Free Electron Lasers (FEL) covering continuously the wavelength range from far-infrared (150μm) down to ultraviolet (150nm), the DELSY storage ring and a vacuum VUV/soft X-ray FEL with minimal wavelength down to 5nm—SASE (Self Amplified Spontaneous Emission) FEL. After complete commissioning of the DELSY facility, we will have a unique light source covering continuously the wavelength range from 1mm down to a fraction of Angstrom. It is important that a significant fraction of the spectrum (from 1mm down to 5nm) will be covered by FELs providing extremely high brilliance of the output radiation.
