The DAFNE Beam-Test Facility (BTF) is a beam transfer line designed for the optimized, stochastical production of single electrons/positrons for detector calibration purposes, or the extraction of the DAFNE LINAC electron/positron beam.
Beam characteristics (spot size, divergence, momentum resolution), are strongly depended by multiplicity (number of particles/spill) and energy requested. Energy range, pulse duration, beam intensity and duty cycle can be limited by DAFNE collider operation.

BTF is part of the AIDA-2020 project in the EC Horizon 2020 Framework Program,
WP15 (JRA3) - Upgrade of the beam and irradiation tests infrastructure.

BTF is part of the ASI-ENEA-INFN agreement ASIF - ASI Supported Irradiation Facilities

BTF-1 beam-line parameters


From 2019, a second beam-line (BTF-2) will be available to the users with similar parameters, but maximum 106 particles/s and energy limited by the selected momentum on the BTF-1 line.
