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.
