  Losses from the proton and antiproton beams of the Fermilab Tevatron have
been shown to produce a halo which contribute to backgrounds to physics signals
in the Collider Detector at Fermilab (CDF). To provide a measure of the beam
halo and losses, we have installed arrays of scintillation counters on both
sides of the CDF detector. We describe here the physical configuration of these
counters, their implementation and performance within the Fermilab Accelerator
Control Network (ACNET). We show correlations between these new devices and the
accelerator operating conditions. We point out that the use of these monitors
is leading to improvement in the accelerator operations and reduced backgrounds
in CDF.
