As Diamond Light Source moves towards its upgrade to a 4th generation synchrotron many of the beamlines are upgrading insertion devices resulting in source points with increased power. Consequently, the power loads expected on the front-end diagnostics will be significantly higher. Simulations of the X-ray beam have shown the power absorbed by the front-end tungsten blades could exceed the...
Very beneficial use is now being made of available vacuum chambers in the Front-Ends of our bending magnet beamlines by installing & operating a newly developed X-BPM that measures (only) the vertical X-ray position at 23m from their source-point.
These simple and low-cost X-BPMs convert through a scintillator screen the hard-rays into visible light, that is being captured and imaged by a...
Optical beam diagnostics at BESSY II is and will further be upgraded for bunch selective measurements at three new beamlines on two bending magnets for visible light and THz radiation. This contribution focuses on the transverse beam-size resolution in addition to other (correlated) beam parameters.
Different methods such as
- double-slit interferometry vs.
- pi-polarization...
ELI Beamlines is an international laser research facility located outside Prague, CZ. Four high-power (up to 10 PW) femtosecond pulse lasers serve as light sources for experiments in several branches of physics. Although control of a high-power laser beam poses different challenges than a synchrotron does, there is a common ground in the operation of support systems, safety, timing, data...
The European XFEL is equipped with cavity, re-entrant and button BPMs up to the dump where the electron beam with up to 17.5 GeV hit graphite. The BPMs near to the dump get additional background signals which decreases the calculated beam position. The problem will be described and I hope we can discuss solutions.
The research and development of the new button BPM initiated by the BESSY VSR upgrade project have progressed in various physical and engineering aspects. Over the past years, the underlying idea such as impedance matching structure has been demonstrated experimentally and engineering details for applying a glass insulator is studied. This presentation will discuss the facts verified in the...
Recent measures at SOLEIL lead us to install the Libera Digit500 on BPM pick ups to check bunch by bunch position evolution during injection.
This presentation will focus on some results and issues we encountered.
We will open the discussion on the behaviors still unexplained and the improvement of this diagnostic.
Technical requirements have long been the main challenge for engineers that had to push the performance boundaries higher and higher. In the last years, the performance challenges were silently replaced by the electronic component availability issue that spread worldwide. Even companies with established supply chains are faced with long and non-predictable lead times, in addition to extreme...
Currently we are in the final design phase of Elettra 2.0. The new machine will have a maximum current of 400 mA, an energy of 2.4 GeV and an emittance of 212 pm-rad. In order to protect the components inside the vacuum chamber and the chamber itself, a beam position interlock is mandatory. In this report we will present the existing interlock system of the current machine, explaining its mode...
A vertical Halo-monitor was installed in this May shutdown, and is now in permanent operation and yielding very satisfying results that will be shown in details, and in relation with studies on the electron beam and the accelerator components like variation of current, filling-patterns, vertical emittance, settings of the undulator gaps, collimators, scrapers etc. and in direct correlation...
