Title: Effect of Vacuum Conditioning on the Bremsstrahlung Dose Rates at the NSLS-II Beamlines

Abstract

Gas bremsstrahlung is produced by the interaction of the storage ring electron beam with residual gas molecules in the storage ring vacuum chamber. Such interactions are one of the sources of stored beam loss, result in beam decay, and occur continuously during the storage ring operation. Gas bremsstrahlung interactions take place all around the storage ring, but are a particular problem in the straight sections for the insertion devices. Bremsstrahlung produced as a narrow beam, sums up for the entire straight path in the line of sight of the insertion device beamlines and comes down through the beamlines along with the synchrotron radiation. The NSLS-II straight beam path in the line of sight for the insertion device beamlines is ~16 m in length. This poses a radiological safety issue at the beamlines.
