The AD Schottky and BTF system relies on rapid acquisition and analysis
of beam quantisation noise during the AD cycle which is based on an
embedded receiver and digital signal processing board hosted in a VME
system. The software running in the VME sets up the embedded system and
amplifiers, interfaces to the RF and control system, manages the
execution speed and sequence constraints with respect to the various
operating modes, schedules measurements during the AD cycle and performs
post processing taking into account the beam conditions in an autonomous
way. The operating modes of the instrument dynamically depend on a
detailed configuration, the beam parameters during the AD cycle and
optional user interaction. Various subsets of the processed data are
available on line and in quasi real time for beam intensity, momentum
spread and several spectrum types, which form an important part of AD
operation today.

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.
