Space Environment Viewing and Analysis Network (SEVAN) extended to Germany

The SEVAN network has been started as a United Nations Basic Space Science Initiative (UNBSSI) project in the International Heliophysics Year 2007 (IHY-2007). A most successful IHY-2007 program was the deployment of arrays of small, inexpensive instruments around the world to get global measurements of ionospheric and heliospheric phenomena.

The SEVAN network aims to improve 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. It also provides reliable, timely and affordable Space Weather forecasting, based on coincident data from the network of particle detectors on Earth's surface and from the space-borne facilities.  SEVAN detectors have been designed and fabricated at the Cosmic Ray Division (CRD). They simultaneously measure fluxes of the most common species of secondary cosmic rays (photons, electrons, muons, neutrons), thus being a very useful device for investigation of cosmic rays, solar flux variations and electron acceleration in thunderstorms. SEVAN modules have so far been operated at the Aragats Space Environmental Center (ASEC) in Armenia, in Croatia, Bulgaria, Slovakia, the Czech Republic and in India. Now, two new SEVAN detectors were installed at DESY Hamburg and Zeuthen.

The data from the whole SEVAN network is an ideal basis of research into exciting phenomena of cosmic rays and solar and atmospheric physics, and especially lends itself to scientific outreach to pupils, school teachers, students, the wider lay public and to decision makers on the value of science in society. The SEVAN network will widely use in these activities.

YerPhI and DESY cooperate in education and training of young students to inspire them for science and technology and to produce skilled scientists and engineers for industries and the general benefit of society. During recent visits of the president of the Republic of Armenia at DESY Zeuthen, and of the directorate of DESY at YerPhi, both sides have expressed their intention to continue and even strengthen this fruitful cooperation of mutual benefit. We are looking forward to it.
