The ALS-U project to upgrade the Advanced Light Source to a multi bend achromat lattice received CD-3 approval in 2022 marking the start of the construction phase for the Storage Ring. Construction of the accumulator under a prior CD-3A authorization is already well advanced. ALS-U promises to deliver diffraction limited performance in the soft x-ray range by lowering the horizontal emittance...
Since the completion of PLS construction in 1994, Pohang Accelerator Laboratory has grown until it become one of the global top 5 facilities which operate 3rd generation synchrotron and X-ray FEL. We are now moving towards new challenges for continuous growth. In this talk, I will discuss about the current status and future direction of PLS-II.
Funding for the Diamond-II Project was announced in September 2023. Diamond-II is a major upgrade of the Diamond facility, covering an upgrade of the storage ring to a low emittance lattice, three new ‘flagship’ beamlines and extensive upgrades to many existing beamlines, a programme of development of core software, controls and computing and the construction of a new building adjacent to the...
The new Elettra 2.0 diffraction limited storage ring facility
The third-generation Italian synchrotron radiation facility Elettra is located on the outskirts of Trieste. It has been serving the national and international scientific and industrial community since 1993, and was upgraded in 2007-2009. The radiation beams, collected and tailored by in-vacuum optical systems, propagate through...
Hefei Advanced Light Facility (HALF) is the diffraction-limited synchrotron light source that is under construction now in Hefei, China.
The storage ring energy is 2.2 GeV, and the natural emittance is about 86pm.rad. Half will be focusing on the sciences conducted with VUV, soft x-ray and tender x-ray. With its high brilliance and coherence, new techniques will be enabled. In this talk, I...
In 2023 BESSY II celebrated 25 years of successful user operation. With over 12.000 publications and 30.000 beamtime proposals from 58 countries continuous demand for this state-of-the-art light source is impressively demonstrated, not least because it mirrors the requirements of a changing user community, scientific needs and societal demands.
BESSY II+ is now the upgrade program to keep...
The possibility to generate low-divergence, high-flux, energy-tunable X-ray beams with a narrow energy bandwidth has long been limited to synchrotron radiation sources based on storage rings with hundreds of meters in circumference. In recent years, there has thus been a growing interest in inverse Compton scattering X-ray sources, as they also allow to generate such X-ray beams of high...
In diffraction limited storage ring or free electron laser beamlines, the thermal deformation control of optical elements under concentrated heat loads is a key technology for wavefront preserving. To cover a photon energy range of 400eV to 1240eV, the beam footprint and flux density distribution on the mirrors will vary significantly when the photon energy changes. Which poses great...
