Scattered high-energy synchrotron radiation at the KARA visible-light diagnostic beamline

“

Radiation protection at synchrotrons requires checking for radiation leakage after changes in the accelerator, beamlines, construction and related shielding. It was a surprise at the visible light diagnostic port when a dose was detected where none was expected. Following the reduction of the dose to an acceptable level a measurement campaign was started to determine exactly what the radiation was together with calculations to understand its source. The work will result in use of both established and new improved detectors to measure leakage and further extension of calculations to better understand and describe high-energy synchrotron radiation.
