The DAFNE BeamTest Facility (BTF) at the INFN Laboratories in Frascati provides electron and positron beams in the energy range tens of MeV-750 MeV in a wide range of intensity, from 1 up to 1010 particles per pulse. The pulse rate is 50 Hz. This paper describes the implementation of two types of high granularity silicon beam monitors: two pairs of silicon strip detectors readout by single particle ASICs for the low multiplicity range (1-100 particles) and a silicon strip detector with charge integrating electronics to cover the remaining range (100-1010). Both the silicon detectors are characterized by large dimensions (up to 9.5×9.5 cm2) and a granularity in the 100 μm range. The paper describes the two systems and the results obtained during several dedicated runs.

Abstract
The DAFNE BeamTest Facility (BTF) at the INFN Laboratories in Frascati provides electron and positron beams in the energy range tens of MeV-750 MeV in a wide range of intensity, from 1 up to 1010 particles per pulse. The pulse rate is 50 Hz. This paper describes the implementation of two types of high granularity silicon beam monitors: two pairs of silicon strip detectors readout by single particle ASICs for the low multiplicity range (1-100 particles) and a silicon strip detector with charge integrating electronics to cover the remaining range (100-1010). Both the silicon detectors are characterized by large dimensions (up to 9.5×9.5 cm2) and a granularity in the 100 μm range. The paper describes the two systems and the results obtained during several dedicated runs.
