The European Synchrotron radiation facility is a third
generation x-ray source providing x-rays on a continuous
basis. As a facility available to external users, the
monitoring of radiation caused by the loss of high-energy
stored beam is of great concern. A network of beam loss
monitors has been installed inside the storage ring tunnel
so as to detect and localize the slow loss of electrons
during a beam decay. This diagnostic tool allows
optimization of beam parameters and physical aperture
limits as well as giving useful information on the
machine to allow the lifetime to be optimized and
defects localized.

Beam loss detectors will play an important role in the
protection of the superconducting LHC magnets.
Different types of detectors have been tested in the SPS
ring and secondary beam lines with a view to their
possible use for this application.
This paper describes the measurements made with:
microcalorimeters at cryogenic temperatures, PIN diodes,
ionisation chambers, scintillators, and ACEMs.
Measurements made using proton beams showing their
relative sensitivities, linearities in counting or analog
mode and minimum detection level will be presented.

Presented in this paper are details of an electronic,
beam position based interlock system, which has been
designed to protect narrow - gap insertion device vessels
from the thermal damage that would result from mis
steered beam. Details of system design and operational
experience are presented, and the paper concludes with an
outline proposal for a system enhancement, that would
offer diagnostic information immediately prior to an
excessive beam displacement trip.
