Collider Upgrade for run IICollider Upgrade for run II
TeVatron at Run II– Main Injector (MI)
120-150 GeV/c p-pbar beams into TeVatron
– pbar Recycler (in MI)
factor x 2 in luminosity
– Machine Parameters:
– Run II Program:
• 132ns by late 2002
• 2x1032cm-2s-1 by end of 2003
• Shutdown for Run IIb silicon
at the end of 2003/2004
• 5x1032cm-2s-1 by 2005
• 4fb-1 / year until 2007
