BEIJING — The 32nd International Cosmic Ray Conference (ICRC 2011), hosted and organized by the Institute of High Energy Physics and the Chinese Academy of Sciences, was held August 11 to 18. Following the tradition of past conferences, the ICRC 2011 dealt with a broad range of topics covering cosmic ray physics, gamma-ray astronomy, solar physics and high-energy phenomena in the atmosphere.

Armenia’s delegation from the Cosmic Ray Division (CRD) of the Artem Alikhanyan National Laboratory (Yerevan Physics Institute) included Bagrat Mailyan, Romen Martirosov and Levon Vanyan, who reported on the research being conducted at the Cosmic Ray Division.

Bagrat Mailyan, a recent PhD recipient, presented two papers on CRD’s research: “Thunderstorm Ground Enhancements (TGEs)” detected at CRD’s Aragats research station and “The energy spectra of the thunderstorm correlated electron and gamma ray fluxes measured at Aragats.” Both talks described research into the new field of gamma rays generated within the earth’s atmosphere by thunderstorms.

Romen Martirosov’s talk was titled, “Energy spectrum and mass composition of primary cosmic radiation in the region above the knee from the GAMMA experiment.” Vanyan discussed “Simulations of the Relativistic Runaway Electron Avalanches (RREA) in the thunderclouds above the Aragats Space Environmental Center (ASEC).”

Medical Diagnostic Consortium In Armenia

In further news about physics in Armenia, on September 2, a memorandum was signed between Armenia’s National Center of Oncology (NCO), the Institute of Informatics and Automation Problems (IIAP), the Institute of Physical Research (IPR) and the Artem Alikhanyan National Laboratory (AANL) represented by their respective directors: H.M. Galstyan, V.G. Sahakyan, A.V. Papoyan and Prof. Ashot Chilingarian.

AANL’s director Chilingarian, in his opening remarks, presented development perspectives for medical diagnostic systems; namely radioactive isotope production for scanners and digital X-ray image detectors for diagnostic imaging.

Galstyan, citing the importance of medical physics research being done at the AANL, outlined the necessity of upgrading currently used X-ray diagnostic devices with modern digital imaging systems. Clinical tests of the detector are to be performed at the National Center of Oncology, using scintillation crystals which are grown in Armenia’s Physical Research Institute.

A memorandum was signed confirming the intention of jointly developing a 3D digital image registration system for mammography. A newly-formed working group of representatives from participating organizations will prepare a development proposal within two months.
