8-Pack Phase 2: SLED Power to eight 60 cm structures. Power 8 structures (a fall back position is 6, +2 powered by NLCTA) Initially structures need to be processed to 75 MV/m (~78 MW) Structures to run at 65 MV/m for a long-term test (~59 MW) Design to minimize technical risk Lower power

8-Pack Phase 2: SLED Power to eight 60 cm structures • Power 8 structures (a fall back position is 6, +2 powered by NLCTA) • Initially structures need to be processed to 75 MV/m (~78 MW) • Structures to run at 65 MV/m for a long-term test (~59 MW) • Design to minimize technical risk • Lower power • ‘Proven’ designs • How important is an ‘NLC-like’ design? • Schedule & cost savings through use/replication of existing designs.
SLED Power with 4 XL4s XL4 50 MW x 4 200 MW 90% to SLED 180 MW x 3.0 540 MW 90% to structures 486 MW 61 MW ~66 MV/m ÷ 8 Need 78 MW to process, 59 MW to run at 65 MV/m
