Cryogenic layout

SIS300 will be supplied in two strings. The total heat load of SIS300 is 3455 W. Therefore the minimum required mass flow rate within one string is 100 g/s.

SIS300 cryogenic equipment

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 0.825 mm diameter

will be manufactured in October 2008 12 km of the wire for three quads will be

necessary in 2009 408 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
