The length of the bunches stored in ESRF lies in the 30 ps to 120 ps
range (FWHM). The observation of single bunch phenomena like transverse
or longitudinal oscillations or bunch length variation requires the
acquisition and analysis of signals at frequencies higher than 10 GHz. A
set of microwave cavity pick ups operating at 10 GHz and 16 GHz together
with the appropriate electronics has been implemented on the ESRF storage
ring; it detects the wall currents on the vacuum chamber due to the
electron beams circulation. We describe the design of these cavities,
give the result and analysis of measurements performed with the pick ups
and indicate how we plan to use these devices as beam diagnostics
