Nearly all modern hadron storage/accumulator rings use an electron
cooling device to increase the phase space density of the circulating
beam before its transfer to another accelerator or to the experiments.
For fast and efficient cooling, the properties of the electron and hadron
beams need to be monitored before, during and after the cooling process
in a non-destructive manner in order not to perturb the normal operation
of the machine. In this paper we review the various techniques used to
measure and optimise the different parameters that determine the quality
of the cooling.
