Role of Multi-Ge. V Proton Sources (FNAL) • Fermilab Multi-MW proton source necessary for Role of Multi-Ge. V Proton Sources (FNAL) • Fermilab Multi-MW proton source necessary for full exploration n sector – No. VA will operate at 700 k. W – Super. Nu. MI could operate in the 1 MW range • Multi-MW proton source is necessary as FE for m source • Multi-MW proton source in EA applications • … • An 8 Ge. V Linac coupled with an upgraded Main Injector is required to get above 2 MW at 120 Ge. V • The 8 Linac b=1 section can be used to ri-circulate and accelerate cooled m’s • The 8 Ge. V Linac idea* incorporates concepts from the ILC, the Spallation Neutron Source, RIA and APT. ~1 Ge. V’sh – Copy SNS, RIA, and JPARC Linac design up to 1. 3 Ge. V – Use ILC Cryomodules from 1. 3 - 8 Ge. V – H- Injection at 8 Ge. V in Main Injector * The 8 Ge. V Linac concept actually originated with Vinod Bharadwaj and Bob Noble in 1994, when it was realized that the MI would benefit from a Linac injector. Gradients of 4 -5 Mev/m did not make the proposal cost effective at the time. Idea revived 2 and expanded by GWF in 2004 with the advent of 20 -25 Me. V/m gradients.

Two Design Points for 8 Ge. V Linac Fermilab • Initial: 0. 5 MW Two Design Points for 8 Ge. V Linac Fermilab • Initial: 0. 5 MW Linac Beam Power – 8. 3 m. A x 3 msec x 2. 5 Hz x 8 Ge. V = 0. 5 MW (11 Klys) • Ultimate: 2 MW Linac Beam Power – 25 m. A x 1 msec x 10 Hz x 8 Ge. V = 2. 0 MW (33 Klys) Either Option Supports: 1. 5 E 14 x 0. 7 Hz x 120 Ge. V = 2 MW from MI • Name of the Game in Linac Intensity: RF POWER – Production (Klystrons) – Delivery to Cavity (PC) 3
