Generating coherent and ultrashort X-ray pulses via HHG-seeding in storage rings [PDF]

Journal of Synchrotron Radiation, 2022
The generation of fully coherent and femtosecond time-scale radiation pulses in the X-ray regime is one of the most common demands of ring-based synchrotron light source users.

Ultralow longitudinal emittance storage rings

Physical Review Accelerators and Beams, 2021
Low longitudinal emittance means small energy spread and short bunch length, which makes high-power short-wavelength coherent radiation possible. In a storage ring, due to quantum excitation, the equilibrium longitudinal emittance is mainly the overall ...

Microcalorimeters for X-Ray Spectroscopy of Highly Charged Ions at Storage Rings

Atoms, 2018
X-ray spectroscopy of highly charged heavy ions is an important tool for the investigation of many topics in atomic physics. Such highly charged ions, in particular hydrogen-like uranium, are investigated at heavy ion storage rings, where high charge ...

Angular Distribution of Characteristic Radiation Following the Excitation of He-Like Uranium in Relativistic Collisions

Atoms, 2021
In this paper, we present an experimental and theoretical study of excitation processes for the heaviest stable helium-like ion, that is, He-like uranium occurring in relativistic collisions with hydrogen and argon targets.

Nanosecond X-ray photon correlation spectroscopy using pulse time structure of a storage-ring source

IUCrJ, 2021
X-ray photon correlation spectroscopy (XPCS) is a routine technique to study slow dynamics in complex systems at storage-ring sources. Achieving nanosecond time resolution with the conventional XPCS technique is, however, still an experimentally ...

The cryogenic storage ring CSR [PDF]

Review of Scientific Instruments, 2016
An electrostatic cryogenic storage ring, CSR, for beams of anions and cations with up to 300 keV kinetic energy per unit charge has been designed, constructed, and put into operation. With a circumference of 35 m, the ion-beam vacuum chambers and all beam optics are in a cryostat and cooled by a closed-cycle liquid helium system. At temperatures as low

New era of synchrotron radiation: fourth-generation storage ring

AAPPS Bulletin, 2021
There had been remarkable progress in developing third-generation electron storage rings as the main sources of very bright photon beams. Fourth-generation storage rings based on the multi-bend achromat lattice concept may be able to surpass the ...

Quasi-isochronous storage rings [PDF]

Physical Review E, 1993
A study is made of the single-particle dynamics of an electron-positron storage ring where the phase-slip factor is made small in order to make the ring nearly isochronous and reduce the bunch length. What is found is that a quasi-isochronous ring makes it possible to obtain a bunch length in the millimeter range, about one order of magnitude shorter ...
