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...
