Description
The Beam Test Facility (BTF) at the National Laboratories of Frascati provides highly flexible electron and positron beams tailored to a wide range of experimental needs. The beam, extracted from the DA$\Phi$NE LINAC, can operate at rates of up to 49 bunches per second, with intensities ranging from a single particle to 10$^{10}$ particles/s. Secondary beams cover energies from 25 to 780 MeV for electrons and up to 550 MeV for positrons.
BTF comprises two experimental areas: BTFEH1, designed for high-intensity and long-duration experiments, and BTFEH2, optimized for low-intensity operation up to 10$^6$ particles per second. Both halls are equipped with remotely controlled movable tables, comprehensive beam diagnostics, and essential services such as laser alignment systems, networking, high-voltage infrastructure, and gas distribution lines, providing full experimental support with continuous 24/7 user assistance.
A key strength of BTF is its user-oriented design, allowing rapid and straightforward beam tuning to accommodate specific experimental requirements, even during data taking. This presentation will describe recent upgrades, including the development of a new control system based on Epik8s (EPICS on Kubernetes), as well as improvements in beam size and energy loss achieved by replacing the 500 µm BeO exit window with a 120 $\mu$m Anticorodal window.
