TL;DR

This paper reports the initial on-ground calibration results of the AGILE satellite's Silicon Tracker, focusing on measuring the Point Spread Function and validating Monte Carlo simulations using a gamma-ray beam at a dedicated test facility.

Contribution

It presents the first calibration results of the Silicon Tracker, including PSF measurements and validation of simulation models, crucial for the satellite's scientific performance.

Findings

01

PSF characterized as a function of photon energy and incident angle

02

Monte Carlo simulation validated against calibration data

03

Calibration setup and preliminary results documented

Abstract

The AGILE scientific instrument has been calibrated with a tagged $γ$ -ray beam at the Beam Test Facility (BTF) of the INFN Laboratori Nazionali di Frascati (LNF). The goal of the calibration was the measure of the Point Spread Function (PSF) as a function of the photon energy and incident angle and the validation of the Monte Carlo (MC) simulation of the silicon tracker operation. The calibration setup is described and some preliminary results are presented.
