Space Environmental Viewing and Analysis Network (SEVAN)

The United Nations Office for Outer Space Affairs and the International Heliophysical Year (IHY) community have joined hands to deploy arrays of small, inexpensive instruments around the world. The small instrument programme is envisioned as a partnership between instrument providers, and instrument hosts in developing countries as one of United Nations Basic Space Science (UNBSS) activity. A network of particle detectors located at middle to low latitudes, Space Environmental Viewing and Analysis Network (SEVAN), aims to improve fundamental research of the particle acceleration in the vicinity of the sun and the space environment. The new type of particle detectors will simultaneously measure changing fluxes of most species of secondary cosmic rays, thus turning into a powerful integrated device used for exploration of solar modulation effects. The first SEVAN modules are under test operation at Aragats Space Environmental Center in Armenia. The network will grow in 2008 by detectors deployed in Croatia, Bulgaria and India. We present the first results of SEVAN module operation as well as a description of the DAQ electronics and software.
