Abstract
The Multi-Bend-Achromat (MBA) structure of the
Diffraction-limited Synchrotron Light Source (DLSR) makes the
dynamic range of its injection significantly smaller, thus posing a
more demanding challenge for the stable injection of beams. To
investigate the possible instabilities during the injection process,
multi-anode photomultiplier tubes (MAPMT) are used in bunch-by-bunch
measurements to obtain the transverse positions and transverse
profiles of the bunched beams as they are injected. However, the
data processing time witnessed in prior measurements posed a
significant challenge in obtaining this information in time, thus
failing to meet the stringent demands of online
measurements. Consequently, this paper proposes one computing
module, engineered to enhance the speed of bunch-by-bunch
measurements of transverse positions and profiles. This solution is
capable of delivering measurement results for each bunch in the
filling pattern, all within the specified injection period.
