May 2022 –

This last April, in Izana in Tenerife (Canary Islands, Spain), at the astronomical site of the Teide Observatory, an important result was achieved towards the installation of the ASTRI Mini-Array. Thanks to a coordinated effort of personnel from INAF, the Fundacion Galileo Galilei, the Temis / CNRS Observatory and with the support of IAC (Instituto de Astrofisica de Canarias), the m-ICT was born. The m-ICT is the mini Information and Communication Technology infrastructure necessary for the management of ASTRI during the first stages of installation.

In fact, every observing facility needs IT support both for operating the instruments on site and to handle the remote connections. This result was also achieved with the precious collaboration of local firms.

The joint effort made it possible to move from the initial paper sketches to a well-coded project and, finally, to this small, somewhat noisy monolith that is the m-ICT.

The m-ICT consists of various parts: the control system of the telescopes, the data acquisition system, which also allows the temporary storage of the acquired data, the monitoring of both the acquisition process and the status of the telescopes, the network that connects the telescopes to the site but also the connection with the outside world via Internet, and finally the temporal characterization system of the data which must assign a label to each datum with the precise indication of the instant of acquisition.

As Fulvio Gianotti, ICT manager for ASTRI on-site recalls: “m-ICT represents a temporary system in a reduced version, suitable for supporting the first phases of the program and in particular the installation of the first 3 telescopes before the final ICT is ready.” The m-ICT was installed in the premises of the CNRS Themis Solar Observatory, also intended to house the control room of ASTRI.

For technical experts, the system operation diagram is described in this figure:

The existence of this small data center has already made it possible to create the first network connection of what will be the public network of ASTRI: With this it will be possible to remotely control the observatory through sophisticated interfaces and transfer data to Italy. For the more curious of you, it is possible to connect to the network at the address: For now, m-ICT will answer you by presenting some slides that tell about its birth!


Con la collaborazione di Fulvio Gianotti

ASTRI is an INAF gamma-ray experiment with the collaboration of other international institutions (P.I. G. Pareschi) with the aim of observing the gamma ray sky from a few to hundreds of TeV by building a Mini-Array of 9 telescopes in Tenerife (Canarie, Spain – thanks to the Instituto de Astrofisica de Canaria, IAC hospitality). The Mini-Array telescopes are similar to those that will be constructed for the CTA project in the south.
