Design considerations of photonic lanterns for diffraction-limited spectrometry

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Challenges in the Design of Diffraction-limited Storage Rings

We review the present developments in the design of ultra-low emittance storage ring light sources those having emittances approaching the diffraction limit for multi-keV X-ray production and the associated design challenges. An overview is presented of the design approaches for these 4 generation storage ring (4GSR) light sources now in construction or being studied for near-term implementatio...

Stretchable diffraction gratings for spectrometry.

We have investigated the possibility of using transparent stretchable diffraction gratings for spectrometric applications. The gratings were fabricated by replication of a triangular-groove master into a transparent viscoelastic. The sample length, and hence the spatial period, can be reversibly changed by mechanical stretching. When used in a monochromator with two slits, the stretchable grati...

Near-Diffraction-Limited Tunable Liquid Crystal Lens with Simplified Design

diffraction-limited storage rings

This article summarizes the contributions in this special issue on DiffractionLimited Storage Rings. It analyses the progress in accelerator technology enabling a significant increase in brightness and coherent fraction of the X-ray light provided by storage rings. With MAX IV and Sirius there are two facilities under construction that already exploit these advantages. Several other projects ar...
