Developments of diagnostics on the 800 MeV High
Intensity Proton Synchrotron of ISIS, the Spallation
Neutron Source at the Rutherford Appleton Laboratory in
the UK, are described. Recent upgrades to instrumentation
and control computers have made much more information
readily available, which is valuable for control of a loss
limited, high intensity machine. Measurements on high
intensity beams have fundamental limitations in terms of
accuracy, detail and interpretation. However, it is found
that use of specially configured low intensity diagnostic
beams can provide much detailed information not
otherwise available, which is extremely valuable after
careful interpretation. The methods and systems being
developed to help trouble shooting, to find optimal
conditions rapidly and systematically, and to improve
understanding of high intensity performance are
described.

RF and digital electronics, developed at the
Forschungszentrum Jülich/IKP were integrated to form
the new beam position monitor (BPM) system at the
Electron Stretcher Accelerator (ELSA) of the University
of Bonn. With this system the preservation of the
polarization level during acceleration was currently
improved by a good correction of the closed-orbit. All
BPM offsets relative to the magnetic quadrupole centers
were determined by the method of beam-based alignment.
The optics functions measured by the BPM system are in
good agreement with theoretical predictions.
