Commissioning of the hybrid multibend achromat lattice at the European Synchrotron Radiation Facility

P. Raimondi et al.

Summary: The European Synchrotron Radiation Facility operates a fourth generation light source with a hybrid multibend achromat lattice that significantly reduces horizontal emittance while maintaining excellent performance. The paper presents beam commissioning experience and results of the ESRF storage ring, focusing on specific challenges related to the HMBA lattice.

Pulse-mode x-ray beam position monitor prototype for a synchrotron radiation beam line

Hideki Aoyagi et al.

Summary: A prototype of an x-ray beam position monitor (XBPM) that can operate in pulse mode was designed and demonstrated, featuring a microstripline structure and a titanium electrode sputtered on a diamond heat sink. The monitor generates unipolar single pulses with a width of less than 1 ns, allowing pulse-by-pulse measurement of synchrotron radiation beam, providing a directly readable position sensitive signal.Tests at the SPring-8 synchrotron radiation beam line showed stability and resolution comparable to conventional XBPMs.

Major upgrade of the synchrotron radiation calculation code SPECTRA

Takashi Tanaka

Summary: Since its first release in 2001, the synchrotron radiation calculation code SPECTRA has been continuously upgraded to address user feedbacks and requests over nearly two decades. However, the complex source code has posed challenges for maintenance and further improvements, prompting a major upgrade in this paper with new features and functions implemented.

Development and application of a tender X-ray ptychographic coherent distraction imaging system on BL27SU at Spring-8

Masaki Abe et al.

Summary: Ptychographic coherent diffraction imaging (CDI) allows visualization of the structure and chemical state of materials on the nanoscale in both soft and hard X-ray regions. A CDI system was developed for the tender X-ray region using high-precision pinholes and a temperature stabilization system, which successfully reconstructed phase and absorption images of materials. This system can be used to visualize the chemical states of light elements on the nanoscale in materials science, biology, and environmental science.
