Abstract

The ESRF has now started its upgrade programme. It has become evident from the start that upgrading beamline performance implies upgrading component performance. Beam stability is seen as a key requirement for many of the proposed beamlines, but the source of (in)stabilities can be manyfold. However, one identified source is white beam mirror, and therefore, ESRF has recently invested significant amount of engineering effort to improve white beam mirror performance. The motivation for having ‘ultra stable mirrors’ at the upgrade beamline ID24 Dispersive Exafs is analysed. The design solutions for positioning, cooling and supporting the white beam mirrors for this project are presented.
