Case Studies for VLHC at/near Fermilab Site (only one tunnel will be needed over the present infrastructure)
Fermilab machine chain as VLHC injector:
Main Injector: 150 GeV (ejection energy)
Tevatron: 150-800 GeV (20% margin)
All options have a dynamic range 10 or less for vlhc.
Low Field aperture: 0.8-5 TeV (0.24-1.5 T)
High Field aperture: 5-50 TeV (1.5-15 T)
Low Field aperture: 0.8-10 TeV (0.12-1.5 T)
High Field aperture: 10-100 TeV (1.5-15 T)
Low Field aperture: 0.8-12 TeV (0.1-1.5 T)
High Field aperture: 12-100 TeV (1.5-12.5 T)
Several other options are also possible.
Can raise the max. field in low field aperture,
hence injection energy in high field aperture.
The proposed common coil magnet system
requires only one new complex for the center of
mass energy up to 200 TeV (option 2 and 3).
