The scientists and engineers of CRD, AANL (YerPHI) visited Germany on October 28 to November 10, 2019 to install two SEVAN (Space Environmental Viewing and Analysis Network) detectors at DESY, Hamburg and Zeuthen. This visit was organized within the framework of SEVAN network, started as a United Nations Basic Space Science Initiative (UNBSSI) project to assist scientists and engineers from all over the world in participating in the International Heliophysics Year 2007 (IHY-2007). 
SEVAN is a network of particle detectors located at middle and low altitudes, which serves the function of improving fundamental research of space weather conditions and to providing short and long-term forecasts of dangerous consequences of space storms. Cosmic Ray Division of AANL (YerPHI) designs and produces the basic particle detector module, front-end electronics and advanced data acquisition system (ADAS). SEVAN network also aims at improving the fundamental research on particle acceleration in the vicinity of the sun, on space weather effects and on high-energy physics in the atmosphere and lightning physics. The network assists in establishing reliable, timely and profitable Space Weather forecasting service, based on on-line information from the networks of particle detectors on Earth's surface and information from the space-borne facilities.
This new type of a particle detector setup simultaneously measures fluxes of most species of secondary cosmic rays, thus being a powerful integrated device for exploration of solar modulation effects and electron acceleration in the thunderstorm atmosphere. The SEVAN modules are operating at the Aragats Space Environmental Center (ASEC) in Armenia, Croatia, Bulgaria, Slovakia, the Czech Republic, in India and now also in Germany. 
The visit of the Armenian scientists (A.Chilingarian, B.Sargsyan, T.Karapetyan) to DESY, headed by Professor Chilingaryan, resulted in the installation of 2 SEVAN detectors at Hamburg and Zeuthen. This is also part of a long-lasting collaboration between DESY and YerPHI which have been active in educating and training students towards their research and in scientific outreach to schools teachers, students and a wider lay public. The data from SEVAN network is particularly instrumental to these activities. 
Both sides agree to share the responsibilities in the following way:
Monitor particle fluxes continuously registering 1-minute time series of different species of cosmic rays and sending the data to the main server of SEVAN network on-premises of CRD.
Support mirror site of main SEVAN database in Germany coping information from main CRD server; 
Conduct training and outreach activities for astroparticle and high-energy atmospheric physics (training events, outreach materials)
Prepare and distribute outreach materials for pupils, school teachers, students and the wider public in German and English language.
Setting up an analysis platform suitable for data from different detector types to be used in school labs at DESY and elsewhere.
Perform simulations of SEVAN detector response function and response to violent solar bursts and Space weather forceful events.
AANL (YerPhI) is in charge of
Maintaining SEVAN network, providing spare parts and consultation;
Maintaining database and ADEI knowledge platform, developing new data analysis methods, including Machine Learning and Bayesian statistical models;
Developing and distributing SEVAN operation manual with methodical materials;
Preparing and distributing a list of outreach and scientific projects to be solved with SEVAN network of different levels ranging from pupil works to master and PhD theses.
Developing the project of SEVAN++, including necessary equipment of moving from particle detector to complete lab for high-level research in the domain of atmospheric physics and climate change.
We are looking forward to continuing the multiyear fruitful cooperation of Armenian and German physicists in this new exciting scientific discipline.
