Common Coil Magnet System (Estimated cost savings by eliminating HEB)

SSC: 20+20 TeV;

VLHC: 50+50 TeV

2 TeV HEB Cost in SSC (derived):

$700-800 million

Estimated for 5 TeV (5-50 TeV vlhc):

~$1,500 million (in 1990 US$)

Cost savings in equivalent 20xx $?

Based on 1990 cost in US$

(Derived based on certain assumptions)

A part of this saving (say ~20-30%) may be used towards two extra apertures, etc. in main tunnel. Estimated savings ~ $1 billion.
