19 Jun 034 F0 Vacuum Upgrade Replacement of A150, P150, P1, Tev US and Tev DS spool sections 3” and 4” diameter Electro-polished, H2 degassed beam tube Addition of Differential Pumping to limit conventional beamline gas loads Addition of TSP in Tevatron Spool sections (must maintain 1e-9 Torr to be effective)

19 Jun 035 Differential Pumping Gas load of A150, P150 and P1 lines are greater than Lamberston gas load (must also consider MI- 60 liner test results) Q(A150) = 5.76e-6 Torr*liter/(sec*cm^2) Q(P150) = 3.96e-6 Torr*liter/(sec*cm^2) Q(P1) = 4.68e-6 Torr*liter/(sec*cm^2) Q(Lam) = 5.28e-6 Torr*liter/(sec*cm^2) Factor of 2 improvement Q(Lam w/ liner) = ?
