The DAΦNE Beam Test Facility (BTF) has been successfully commissioned in
February 2002, and started operation in November of the same year.
Although the BTF is a beam transfer line optimized for single particle
production, mainly for high energy detectors calibration, it can provide
electrons and positrons in a wide range of multiplicity: between 1-1010,
with energies from a few tens of MeV up to 800 MeV. The large
multiplicity range requires many different diagnostic devices, from
high-energy calorimeters and ionization/fluorescence chambers in the few
particles range, to standard beam diagnostics systems. The schemes of
operation, the commissioning results, as well as the beam diagnostics are
presented.

At the DAΦNE collider a beam loss monitor system has been installed to
continuously monitor the particle losses. The acquisition is based on 32
Bergoz beam loss monitors, of the Wittenburg type, installed close to the
main rings vacuum chamber, buffering monitoring circuitry and a counting
scale (SIS 3801) as acquisition board. We developed a front-end software
that allows acquiring the integrated value of the BLM counts and a stream
of 1000 point for each monitor, to cover an history of 3000 s. The
operator program allows displaying the instantaneous BLM values over the
machine together with a representation of the past history.
