Cross section of
SIS300 quadrupole cold mass
Questions to be settled ASAP
with GSI experts
• Main parameter list for SIS300 quadrupole
• Elements of protection system including evacuation
of helium at quench of SIS300 magnets
• Cryogenic system for SIS300 magnets
• Design of supports for quadrupole cold mass and
thermal shield
• Design of quadrupole beam pipe
Tentative production schedule
for SIS300 quadrupoles
Conclusion
IHEP has scientific and technical potential
adequate for production of quadrupoles for the
SIS300
IHEP presented the relevant EoI and put
forward a tentative specification list for a SIS300
quadrupoles
More detailed SIS300 quadrupole design calls for
a thorough matching with the other SIS300
subsystems
