The LHAASO (Large High Altitude Air Shower Observatory) experiment is currently under installation at high altitude (4410 m a.s.l., 600 g/cm2) in the Daocheng site, Sichuan province, P.R. China, with the aim of studying with unprecedented sensitivity the spectrum, the composition and the anisotropy of cosmic rays in the energy range between 1012 and 1018 eV, as well as to act simultaneously as a wide aperture (about 2 sr), continuously operating gamma-ray telescope in the energy range between 1011 and 1015 eV. One of the main detectors of LHAASO is constituted by an array of 18 wide field of view (16°×16°) Imaging Atmospheric Cherenkov Telescopes (IACTs). Unlike the usual IACTs dedicated mainly to gamma-ray astronomy, these telescopes will be devoted to the study of the energy spectrum and elemental composition of the cosmic rays around the "knee" of the all-particle primary spectrum (at about 3 1015 eV). The focal plane of these telescopes being made of SiPMs, dedicated Front-End (FE) and Slow Control (SLC) boards must be designed with the needed amplification and bandwidth features to achieve the required wide dynamic range of 10-32,000 photoelectrons. In this paper, the electronic scheme and the components selection of these boards are presented and discussed.

Abstract
The LHAASO (Large High Altitude Air Shower Observatory) experiment is currently under installation at high altitude (4410 m a.s.l., 600 g/cm2) in the Daocheng site, Sichuan province, P.R. China, with the aim of studying with unprecedented sensitivity the spectrum, the composition and the anisotropy of cosmic rays in the energy range between 1012 and 1018 eV, as well as to act simultaneously as a wide aperture (about 2 sr), continuously operating gamma-ray telescope in the energy range between 1011 and 1015 eV. One of the main detectors of LHAASO is constituted by an array of 18 wide field of view (16°×16°) Imaging Atmospheric Cherenkov Telescopes (IACTs). Unlike the usual IACTs dedicated mainly to gamma-ray astronomy, these telescopes will be devoted to the study of the energy spectrum and elemental composition of the cosmic rays around the "knee" of the all-particle primary spectrum (at about 3 1015 eV). The focal plane of these telescopes being made of SiPMs, dedicated Front-End (FE) and Slow Control (SLC) boards must be designed with the needed amplification and bandwidth features to achieve the required wide dynamic range of 10-32,000 photoelectrons. In this paper, the electronic scheme and the components selection of these boards are presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
