and Emilio Segre’ Observatory
November 27, 2000
The aims of the Project for the third year (February 2000-January 2001) are as follows:
· Development of the Emilio Segre’ Cosmic Ray Observatory.
· Development of the ICRC Laboratory in Qazrin.
· Establishment of a direct connection between the Emilio Segre’ Cosmic Ray Observatory and our Computer in MIGAL (Kiryat Shmona), and between MIGAL and the ICRC Laboratory at Qazrin.
· Establishment of the page in Internet of the Israel Cosmic Ray Center, with information on the Emilio Segre’ Cosmic Ray Observatory and on cosmic ray observations in real time scale.
· Continue the research program in Cosmic Ray Astrophysics and Geophysics, participation in International Conferences and Symposia.
· Establishment of collaboration with other Cosmic Ray Observatories and data exchange in real time scale.
· Development of the analytical methods of forecasting anomalous Cosmic Radiation events, representing changes in the Interplanetary and Near-Earth environment. Such events could possibly be harmful to space-probes, to earth orbiting equipment, to air-travel, to electromagnetic communications and perhaps even to living beings on Earth. Phenomena which might indicate such developments include, for example, large solar flares, the impacting of energetic particles and Forbush-decreases connected with large geomagnetic disturbances. The network of observatories providing such early-warning services will form the “International Cosmic Ray Service”.
THE STAFF OF ICRC AND DEVELOPMENT OF THE LABORATORY IN QAZRIN
Israel Cosmic Ray Center was established in 1998, with affiliations to
· In 2000 the Laboratory was equipped with additional computers. The local network was set up, with a sufficient increase of the existing capacities of the memory and hard discs.
· In 2000 we completed the foundation of direct connection in real time of the Emilio Segre’ Observatory with our Laboratory in Qazrin and with Internet (updated each one minute, see Appendix 1).
DEVELOPMENT OF THE ISRAEL-ITALIAN EMILIO SEGRE’ OBSERVATORY
2000 we continued to operate the Cosmic Ray Neutron Monitor in the Israel-Italy
Emilio Segre’ Observatory (33°18.3¢N, 35°47.2¢E,
· The results of measurements – data taken at one minute intervals -- of cosmic ray neutron intensities at two separate sites, as well as similar one-minute data about the intensities relating to neutron multiplicities ³1,³2, ³3, ³4, ³5, ³6, ³7 and ³8 – all of this data has been computer-stored. Similar one-minute data relating to the atmospheric electric field, wind speed, air temperature and pressure outside the Observatory, as well as temperature and humidity inside the Cosmic Ray Observatory – have also been recorded.
· Each month one-hour data of the Emilio
Observatory (short title ESOISR) is
regularly sent to the
· An automated electric power supply system, based on UPS and Diesel-generator, established in 1999, continued to work well in 2000.
· A direct, "real time" connection has been set of the Emilio Segre’ Observatory through MIGAL with the Central Laboratory in Qazrin and Internet (updated each 1 minute).
