Time schedule

Production of SIS300 quads SIS300 quads design, production, test, delivery to FAIR, installation in tunnel – IHEP Production of SC cable from 19 strands - IHEP Development and production of superconducting wire - FSUE VNIINM : 1 km length SC wire of mm diameter will be manufactured in October km of the wire for three quads will be necessary in km (2 tons) of the wire for 102 quads in 2010 – 2011

Production of SIS300 multipoles SIS300 multipoles design, production, test, delivery to FAIR, installation in tunnel – IHEP NIIEFA is ready to take part in calculations and test of the multipoles. Participation in production of the magnets will be discussed after completion of their design by IHEP. Development and production of superconducting wire - FSUE VNIINM (parameters of SC wire will be determined)

Production of SIS300 Local cryogenics IHEP plans calculations of SIS300 cryogenic system and preparation of Technical Specification for equipment of the system in collaboration with GSI, CRYOGENMASH, GELIYMASH CRYOGENMASH, GELIYMASH will design, produce, deliver to FAIR and arrange the cryogenic equipment in collaboration with IHEP

Research possibility for young specialists in SIS300 development
