ABSTRACT: |
For the optimisation of the photon brilliance on the ESRF Synchrotron Light Beamlines the large majority of the 32 vacuum sectors of the e- Storage Ring has been equipped with flat, conductance-limited Insertion Device (ID) vacuum vessels made from aluminium extrusion. For chambers with an inner vertical aperture as low as 8mm the application of Non-Evaporable Getter (NEG) coating was the only way to archive acceptable Bremsstrahlung conditioning times, thus minimizing the downtime of the connected Beamline due to high radiation levels. |
