• SEVAN detector installed on Zugspitze in Bavarian Alps (Apr 26, 2023)
  
  Armenian and German SEVAN groups established the SEVAN module at the Environmental research station Scheefernhaus (Zugspitze, 2650 m). A historical site where Johim Kuettner performed seminal experiments on the charge structure of the thundercloud in 1945-1949. The near-surface electric field (NSEF) measurements will support particle flux measurements with the EFM-100 sensor...
• Climb to Aragats (Duty shift change in February) (Feb 8, 2023)
  
  The Aragats Cosmic Ray observatory, used for studying particle acceleration in outer space and the terrestrial atmosphere (see attachment), is located at an elevation of 3200 m . asl (above sea level) on the shore of Kare Lake (Kari Lij). Strong winds, predominantly from west to northwest, relocate large amounts of unconsolidated winter snow, accumulating on the sheltered...
• New Discoveries of Aragats Physicists (Jan 6, 2023)
  
  The first years of Armenia's independence were very difficult for the staff at Yerevan Physics Institute’s Cosmic Ray Division (CRD). With funding suddenly stopped from the largest soviet ministry, there was no fuel, electricity, and food. Monthly salaries were the equivalent of five U.S. dollars. The construction of the world’s largest cosmic ray experiment, ANI...
• Continuation of TEPA conference series in the Czech Republic (Nov 4, 2022)
  
  The new emerging field of high-energy physics in the atmosphere (HEPA) has been enriched recently by important observations of particle fluxes on Earth’s surface, in the troposphere, and in space. HEPA presently includes three main types of measurements: Terrestrial Gamma Ray Flashes (TGFs) – brief bursts of gamma radiation (sometimes also electrons and positrons)...
• О шаровых молниях - как возможном источнике фотонов (Dec 10, 2021)
  
  3 декабря в ЛФВЭ в онлайн-формате состоялся общелабораторный семинар, на котором с докладом "Шаровая молния как возможный источник фотонов высоких энергий" выступил  М.Л.Шматов (Физико-технический институт имени А.Ф.Иоффе РАН, Санкт-Петербург). Вообще предположения об испускании шаровой молнией ионизирующего излучения, в основном...

• Maximum strength of the atmospheric electric field (Mar 1, 2021)
  
  PHYSICAL REVIEW D 103, 043021 (2021)  Understanding the maximum potential difference (i.e. voltage) inside thunderstorms is one of the fundamental problems of atmospheric physics directly connected with the enigma of the lightning initiation. In 1925 C.T.R. Wilson estimated the maximum potential difference in the atmosphere to be a few gigavolts:...

  ARMENIAN PHYSICISTS PARTICIPATE IN BREAKING THE LIMITS: DISCOVERY OF THE HIGHEST-ENERGY PHOTONS FROM A GAMMA-RAY BURST Gamma-ray bursts (GRBs) are the most violent explosions in the Universe, suddenly appearing in the sky, about once per day. They are thought to result from the collapse of massive stars or the merging of neutron stars in distant galaxies. The first GRB...
• Space Environment Viewing and Analysis Network (SEVAN) extended to Germany (Nov 18, 2019)
  
  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...
