  A means for non-invasive measurement of transverse and longitudinal
characteristics of bunched beams in synchrotrons has been developed based on
high sensitivity slotted waveguide pickups. The pickups allow for bandwidths
exceeding hundreds of MHz while maintaining good beam sensitivity
characteristics. Wide bandwidth is essential to allow bunch-by-bunch
measurements by means of a fast gate. The Schottky detector system is installed
and successfully commissioned in the Fermilab Tevatron, Recycler and CERN LHC
synchrotrons. Measurement capabilities include tune, chromaticity, and momentum
spread of single or multiple beam bunches in any combination. With appropriate
calibrations, emittance can also be measured by integrating the area under the
incoherent tune sidebands.
