The PTB, Germany´s national metrology institute, has relied on synchrotron radiation for metrology purposes for over 40 years and the most prominent customers are lithography systems from ASML/ZEIS. HZB is now working on a concept for a BESSY II successor, based on a 4th generation light source with an emittance of 100 pmrad @ 2.5 GeV. It is essential, that this new facility continues to serve...
While multi-bend achromat lattices combined with technological advances opened the way toward ultra-low emittance storage ring light sources, a number of practical and theoretical factors limit their design performances. We examine these factors through lattice design practices and explore the optimal design approach for a diffraction limited storage ring in the hard X-ray regime.
Picosecond-long x-ray pulses of moderate intensity and high repetition rate are highly sought after by the light source community, especially for time-resolved fine spectroscopic analysis of matter in the linear response regime. We investigate the upgrade of the Elettra 2.0 diffraction-limited storage ring light source to radiofrequency transverse deflecting cavities generating a steady-state...
SOLEIL II is a project aiming at upgrading the present SOLEIL synchrotron to a fourth-generation light source. The photon spectral performances such as brightness and flux density will be highly increased by a drastic decrease of the natural horizontal emittance, below 100 pm.rad. The goal will be accomplished by an increase of the number of magnets and the compactness of the equipment. Big...
Abstract. A significant amount of cryogenic permanent magnet undulators (CPMUs) were deployed in the past at the ESRF with significantly more overall emitted spectral power and reduced gaps [1, 2]. Further insertion device (ID) upgrade plans exist with double (2x2m) CPMU arrangements and possible high-temperature superconducting IDs.
The drastically increased emission of photons and...
We have been exploring a novel method to fabricate undulator magnets having a very short period length of a few mm. Plate monolithic magnets (PMM) made of Nd-Fe-B, 100mm long with 4-mm period length have been successfully fabricated[1-4]. The 4-mm period length allows us to obtain 12-keV radiation with the first harmonic of this undulator in the 2.5-GeV light source accelerator. A connection...
