The ASTRI project represents an effort of an international collaboration led by the Istituto Nazionale di Astrofisica, Italy, in conjunction with the Universidade de Sao Paulo, Brazil, and the NorthWest University, South Africa, aiming at assessing the technology of an array of smallsize Cherenkov telescopes (SSTs). In this respect, the ASTRI-Horn telescope, an end-to-end prototype, has been installed in Sicily, on the slopes of the Etna volcano at 1735 m a.s.l. The telescope is characterized by a dual-mirror Schwarzschild-Couder design that covers a wide field of view and favors gamma-ray observations in the range from few TeVs up to tens of TeV. Its curved focal-plane camera consists of Silicon-photomultipliers, which are controlled by fast front-end electronics. The complete end-to-end approach includes the implementation of calibration as well as control and acquisition systems, together with the data reduction, archiving and analysis software. The ASTRI collaboration has successfully completed the commissioning and science verification phase of the prototype, including observation of the Crab Nebula. A mini-Array composed of nine ASTRI telescopes is being developed and operated by INAF in the context of the preparatory effort for the proposed participation in the Cherenkov Telescope Array (CTA). Apart from a few minor changes implemented to improve the telescope design, the mini-array telescopes will be very similar to the ASTRI-Horn telescope. In this contribution an overview of the main features and performance of the ASTRI-Horn telescope is presented together with recent updates and first scientific results. In addition to this, the technological evolution towards the ASTRI mini-array and its scientific expectations are outlined.

“…As the southern site chosen for CTA has no volcanos in the immediate environment and no aggressive atmosphere, the rate of degradation should be in line with CTA requirements. The electromechanical structure has been intensively studied and its parameters have been optimized to achieve the maximum performance as thoroughly described in [6]. As part of regularly scheduled activity, an observational campaign to monitor the tracking and pointing performance as well as the astrometric precision of the telescope between November 2017 and January 2018 has been carried out.…”

“…While LSTs provide sensitivity at the lowest energies (20 < E < 150 GeV), SSTs are optimised to the highest VHE energies (5 < E < 300 GeV; [3]). There are currently three different SST prototypes under development within the CTA Collaboration, i.e., the single-mirror SST [4] and the dual-mirror (2M) telescopes GCT [5] and ASTRI [6]. The latter is conducted by the Italian National Institute for Astrophysics (INAF) since 2011 with the aim to design and develop within the CTA framework an end-to-end prototype of the SST in 2M configuration.…”

The ASTRI dual-mirror small-size telescope (ASTRI-Horn) is an imaging atmospheric Cherenkov telescope that was developed by the Italian National Institute of Astrophysics (INAF) within the framework of the Cherenkov Telescope Array (CTA) project, the next-generation ground-based very-high-energy gamma-ray observatory. The CTA observatory will consist of two sites configured in two arrays of telescopes of different sizes. They will be located in the Northern and Southern Hemispheres to cover the full sky. ASTRI (Astrofisica con Specchi a Tecnologia replicante Italiana) is the Italian proposal for the small-size telescopes and its design is based on a Schwarzschild-Couder configuration. To fulfill the required plate scale, the camera is based on a new technology involving the use of Silicon-photomultipliers. With its wide field of view of 10 degrees, it is optimized for gamma-ray observations in the range from few TeV up to several tens of TeV. The ASTRI prototype is installed at Serra La Nave at 1735 m a.s.l. in Sicily, Italy, and is currently going through the science validation phase. A further development of the program foresees the construction of a set of nine ASTRI telescopes proposed as pathfinder for the CTA array. In this contribution, the main features of the ASTRI telescope will be described and an update on the latest news on the prototype activities and the mini-array will be presented.
