CRD’s SEVAN Network Expands to India’s Jawaharlal Nehru University

YEREVAN — The ability to forecast space weather storms is vital for the security of space based electronic systems as well as the power grid delivering power to homes and industry. Armenia’s Cosmic Ray Division is expanding its network to monitor and forecast space weather events.

The Cosmic Ray Division (CRD) of Yerevan’s Alikhanyan Physics Institute recently announced the expansion of its Space Environment Viewing and Analysis Network (SEVAN) into India. The SEVAN system consists of an internationally networked array of terrestrial cosmic ray detection systems at middle to low latitudes. Data from these installations is sent via Internet to CRD’s research center in Yerevan where it is analyzed and shared with international research partners throughout the world.

The SEVAN network aims to improve fundamental research studying the mechanisms of cosmic ray particle acceleration in the vicinity of the sun and in other space environments to advance the Space Weather alert systems. New types of particle detectors, invented by CRD scientists and deployed within the SEVAN network, simultaneously measure changing fluxes of most species of secondary cosmic ray particles. Piecing this information together from world wide SEVAN installations, including precise timing information, allows scientists to predict dangerous solar radiation storms tens of minutes before their arrival from the sun. SEVAN’s data also allows scientists to forecast damaging geomagnetic storms hours before their arrival. These storms, resulting from huge clouds of plasma traveling from the sun towards the earth at speeds up to 4.5 million miles per hour, can cause extensive damage to communication systems, power grids and pipelines.

The first four SEVAN modules became operational at CRD’s Aragats Space Environmental Center on the slopes of Armenia’s Mount Aragats. In 2009 additional SEVAN installations were deployed in Croatia and Bulgaria. In the fall of 2010 a SEVAN detector was installed in the Remote Sensing Applications Laboratory, School of Environmental Sciences, Jawaharlal Nehru University, New Delhi, India. This year’s plans call for a SEVAN unit to be installed in Slovakia.

Reliable forecasts of the major geomagnetic and radiation storms are of great importance due to the danger they pose to major space-based systems such as the Global Positioning System (GPS) and communication satellites. Radiation storms also pose a radiation hazard to astronauts in space and crews and passengers aboard aircraft.

    The CRD is *vitally* important to keep talented scientists in Armenia.

    No modern country,and especially one surrounded by Turks, can survive without scientists. Support CRD!

    The Cosmic Ray Division of Armenia produces some of the most remarkable work in the world, and with very few resources.

    Imagine what they could do with our financial assistance.

    CRD and SEVAN project’s success is the key to international recognition for the telented Armenian scientist in Armenia. They deserve diaspora Armenians gererous support.

    these scientists accomplish so much on a shoe string budget. Support the CRD scientists so they can continue their amazing work on top of Mt. Aragadz.

    It is a great pride to know that Armenian scientists in Armenia, against all economic constraints, put together their talents and have reached into the international scientific arena in a leadership role. Your support encourages the Armenian brilliant minds to use their talent to explore the outer edges of the universe, learn about our galaxy, and research solar effects on the space environment around our planet. We have an immense opportunity to support CRD’s Space Education program in Armenia. Support CRD.

    Abrees Takoui!
    I share Takou’s statememt. I was there last summer. It was amazing to see how they work!
    We all have to support CRD. It is our honor!
