Sources

Elettra 2.0 will incorporate new sources and cutting-edge technologies, such as two superconducting bending magnets with a 6 T peak field, extending the X-ray spectrum to energies of up to 130 keV for the SYRMEP-LS and Xpress beamlines. 
New short-period in-vacuum LPUs will be installed to extend the photon energy range into the hard X-ray regime, reaching up to 20 keV. With period lengths between 17 and 22 mm, these LPUs will serve as highly brilliant sources for the new m-diffraction, m-fluorescence, and HB-SAXS flagship beamlines.

Two new EPUs have been specifically designed and constructed for the upcoming CDI beamline. This unconventional set-up incorporates a magnetic phase shifter between the two undulators, enabling the generation of linearly polarized radiation without on-axis higher harmonics—an advantage for several experimental setups.

Several novel insertion devices will also be positioned in the short straight sections of the storage ring, including a compact EPU with a 32 mm period, designed to cover the tender X-ray range with adjustable polarization. This device will serve as the source for the future APE-TX beamline.

For the relocated XRD-1 beamline, a short 1.8 T wiggler has been manufactured. Despite having only 15 poles, it offers higher critical energy and brilliance compared to the previous 4.5 m long, 1.5 T device. Its design also reduces the multiple-source effect, ensuring more uniform sample illumination.

Additional compact undulators include:

• An adjustable-phase LPU for the upgraded TwinMic beamline;
• A switchable-period LPU for ALOISA, extending its photon energy range.

Five beamlines will depend on radiation from the 1.46 T bending magnets.

Several existing insertion devices will be repurposed for use in the new machine, particularly during the initial operational phase. These include:

• Linearly Polarized Undulators (LPUs): from the SuperESCA beamline.
• Elliptically Polarized Undulators (EPUs): from Nanospectroscopy/NanoESCA, MOST, BACH, and APE.
• Figure-8 Undulator: from the Spectromicroscopy/BaDElPh beamline.
• Superconducting Wiggler: from the HF-SAXS, MCX beamlines and initially also for the Xpress beamline
