Due to the limited transverse acceptance of fourth generation light sources, the characterization and control of the incoming beam from the booster to the storage ring is an important asset to achieve highly efficient and reproducible injection.
For the up graded Swiss Light Source (SLS 2.0) storage ring, a new booster to ring transfer line (BRTL) has been designed with a non dispersive...

As SLS 2.0 transitions from machine commissioning to full beamline commissioning and user operation, the demands on long-term reliability and high availability of the accelerator complex increase significantly. Ensuring minimal downtime requires fault-handling mechanisms that are both rapid and systematic, enabling the machine to respond safely and consistently to unexpected conditions. This...

The European X-ray Free-Electron Laser (Eu-XFEL) currently operates in a pulsed mode, delivering ultra-short, high-intensity X-ray pulses for a wide range of scientific applications. However, transitioning to a continuous-wave (CW) operation mode could significantly enhance its capabilities by enabling higher average brightness, improved temporal coherence, and novel experimental...

An FPGA-based platform has been developed in-house for the Electron Beam Position Monitor (eBPM) systems of Elettra 2.0, the ongoing upgrade of the Italian synchrotron toward a higher brilliance lightsource. Leveraging its modularity and high processing capabilities, this platform has been extended to various subsystems, including the Digital Low-Level Radio Frequency (DLLRF).

After the successful testing of the BBQ system for passive tune measurements using direct diode detectors at the SOLARIS storage ring, the next step - and a significant challenge - was the proper acquisition and processing of the analog signal. To address this, a 24-bit ADC system integrated with a Zynq FPGA was developed to ensure high-quality signal acquisition and reliable data...

The commonly used bunch length diagnostics in electron storage rings is the streak camera, fed by visible synchrotron light. Although this instrument is able to precisely measure the shape of very short longitudinal profiles of idividual bunches, it also has a major disadvantage: its photocathode is subject to aging upon permanent exposure to incoming light. It is therefore mainly used for...

Lorraine Bobb (Diamond Light Source)23/03/2026, 14:55Presentation
X-ray pinhole cameras are still the preferred option for emittance measurement in synchrotron light sources due to their simplicity in design, operation and data analysis. It has been observed over many years at multiple facilities, that a structure similar to a diffraction pattern is observed when the electron beam size is squeezed. This effect is called filamentation and has been identified...

We present signal and thermal measurements from the first prototype of a stripline Beam Position Monitor (BPM) intended for the PETRA IV synchrotron ring. The monitor was installed at the PETRA III testbed for evaluation and compared against CST Studio Suite simulation results. Initial measurements revealed unexpected signal oscillations and significant heating (up to 135 °C), which were not...

Electromagnetic resonances localized near Beam Position Monitors (BPMs) can significantly distort the beam induced signal on the electrodes and compromise BPM readings. At the European Synchrotron Radiation Facility (ESRF), a detrimental resonance was identified in the vicinity of a BPM. It originates from a small break in the electrical continuity (~2-3µm) due to the nearby RF gasket that...

Accurate knowledge of the longitudinal phase of individual bunches relative to a reference RF signal is essential for applications that demand tight synchronization, such as bunch‑by‑bunch transverse or longitudinal feedback systems. While many beam‑phase diagnostics exist, they are not always optimal with sparse‑filling or single‑bunch operation.
Here we would like to discuss a method for...
