Review of the radiation effects at the ESRF

摘要

This paper presents the effects of synchrotron radiation (i.e. X-rays of high energies), combined with the associated parasitic radiation, on equipment of a third generation Synchrotron Light Source after seven years of X-ray beam delivery. Dose measurement data is associated with the observed radiation damage. The future ID6 beamline experiment is described. This irradiation bench will be dedicated to test the behaviour of standard materials (mainly electric cables and cooling hoses) with hard X-rays. The aim is to identify more radio-resistant components to replace the damaged ones. Various ways to reduce the electron beam losses are also presented, with their associated effects.
