The current communications infrastructure at YerPhI has been developed beginning from 1994-1995 and mainly based on 10Mbps Ethernet technology. Later development 2001-2002 by using DESY supported old 10Mbps switches mainly concerned with sufficient enlargement, but actually information backbone itself and its topology remain unchanged. Last development was 2005- 2006 NATO Networking infrastructure project. In the framework of that project 4-wire Fiber optic cable are installed between 6 buildings of Yerphi. The new layer-II switches (one per building) were installed. User level network still manly based on 10 MB Hubs and hub-segme ...

There are about 15 scientists, engineers, technicians, and 4 graduate and postgraduate students working in different groups. The first Internet connection in Armenia based on satellite connection via DESY (Hamburg) was realized in 1994 at AANL (YerPhI). The IT group provides a number of services: Domain Name Service (DNS); E-Mail services (SMTP, POP, IMAP), Webmail, Mailing Lists Basic services; Internet accessible Information and Database Systems; Secure Data Transmission (VPN, SSH, SFTP, SSL, S-tunnel); Remote Administration; Web Hosting; Archive, Backup, Data Storage and data Preservation; Antivirus, Antispam, Antispyware support; Voice and Video Conferencing; WiFi And Eduroam (education roaming) world-wide Wifi roaming access service for international research and education community; Video media server; Document Server (Invenio CERN/IAEA). Several powerful UNIX servers (Super-Micro, Dell) installed at AANL are equipped with all necessary modern High Energy Physics (HEP) libraries and tools, like CERN libraries, “Mathematica”, “ALPS” (for parallel computations), also with Python oriented machine learning libraries and tools.

The activities related to the Computational Physics and Data Analysis sub-direction include:

studies of statistical features of new pseudo-random numbers generator MIXMAX, developed at AANL (N. Akopov, G. Savvidy), which is one of the best world generators as to the statistical features and record period.

development and creation of the new effective approach with essentially lower time and memory consumption to calculate the multidimensional Kolmogorov-Smirnov test. These works were supported by the European Union's Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement No 644121.

Physical analysis of the data collected by HERMES experiment in spin physics and hadrons formation phenomena.

New Belle II Experiment at Super KEKB Japan on asymmetric electron-positron collider: Ee+=4 GeV and Ee-=7 GeV (in cooperation with DESY), where the data collection has been underway since 2019 and it is planned to study very interesting and important for modern HEP phenomena like: B physics (rare decays); CP violation in B decays; Tau physics (rare decay studies); Searches for the New Physics beyond the Standard Model, dark photon searches. Two seniors, one PhD and three master-students are working in this group on detectors performance studies as well on physics analysis, participating in regular video-meetings, reporting the group results also on main BelleII collaboration meetings, taking the local and remote shifts. Three papers are already been published by BelleII with the co-authors from AANL. The rate of expected publications in the leading world journals will be on the level of (30-40)/year. We are going to involve 2-3 more students in this direction, which is very promising and attractive for young people and will be acting at least next 25 years (long future). The AANL group is continuing traditional cooperation (HERMES, OLYMPUS) with DESY(Germany) also in this direction. The BelleII experiment is the most advanced in the world in sense of using the modern approaches and algorithms like machine learning and AI. This is very important and useful for young people and stimulates the corresponding development of IT infrastructure at AANL. The results of HERMES and BelleII experiments are reported in various international conferences.
