Description
The 6GeV electron beam shows since long tiny variations of its energy that can now be measured by a suitable use & treatment of the horizontal position from (128) dispersive BPMs, and also more recently by a simple X-ray detector installed on an available X-ray beam port equipped with a 3-pole wiggler. These 2 fully independent results are now recorded permanently and their analysis allows to distinguish fine details of these variations that are often induced by urban activity in the Grenoble area.
The principle, the characteristics and the main components of these measurement systems will be described, together with the obtained results.
