The DAFNE Beam-Test Facility

The DAFNE Beam-Test Facility (BTF) is a beam transfer line which has been designed in order to optimize the operation mode in which single electrons are stochastically produced for detector calibration purposes. Beam characteristics (spot size, divergence, momentum resolution), are strongly depended by multiplicity (number of particles/spill) and energy requested. Energy range and duty cycle are limited by DAFNE main ring operation.

Energy Range 25-750 MeV e-/e+
Max. Repetition Rate 50 Hz
Pulse Duration 1-10 ns
Particles/Pulse 1 to 1010 particles
