JINR Technical Policy and Infrastructure In order to improve and develop the technical policy and infrastructure at JINR, a supplement to the Programme of JINR’s Scientific Research and Development for the years 2003-2009 will be prepared for the session of the 95th Scientific Council (January 2004). This activity has been started by a working group. This group was established by the JINR Directorate. The supplement will include the status, proposals of maintenance and development as well as requests for necessary resources in 2003-2009 for: •Basic facilities •Energy, heating and water •Experimental workshops •Technical infrastructure of laboratories •Radiation, nuclear and industrial safety •Information technologies •Buildings, Transport, Social infrastructure •Staff policy G.Shirkov, Basic Facilities, JINR Scientific Council, 05.06.2003 3. Problem of Young Staff for JINR number 250 JINR staff by age 200 1989 2003 150 100 50 0 age The main reason for the aging of the JINR personnel: JINR is not attractive for the younger generation now due to: • low salary; • limit of modern scientific equipment in Laboratories; • housing and living problems; • social problems A special group was recently organized in order to study ways of making JINR more attractive for young scientists and workers. 16 19 22 25 28 31 34 37 40 43 46 49 52 55 58 61 64 67 70 73 76 79 82 85 G.Shirkov, Basic Facilities, JINR Scientific Council, 05.06.2003
