The conceptual design for the RPI 2020 L-band Linac relies heavily on the experience of the people who designed, commissioned and operate several linear accelerators at SLAC, the longest of which is the SLAC 2-mile S-band linac. In addition the conceptual design owes much to the close cooperation with scientists and engineers at Rensselaer Polytechnic Institute (RPI) and Bechtel Marine Propulsion Corporation Knolls Atomic Power Laboratory (BMPC-KAPL), who have formulated the goals of the future machine and provided the necessary detailed information about existing infrastructure and capability at RPI. Finally the RPI 2020 Linac Design Study Group is a list of people, authors and non-authors, who have contributed significantly to this conceptual design.

In the process of completing this conceptual design for the RPI 2020 Linac, we have held one kickoff meeting at RPI, several phone meetings with RPI and BMPC-KAPL, an internal review at SLAC, presented an interim draft to RPI and BMC-KAPL half way through the process, incorporated BMPC-KAPL and RPI returned comments into the draft report, presented a final fraft to BMPC-KAPL and RPI, held a close-out meeting with BMPC-KAPL and RPI at SLAC, and incorporated BMPC-KAPL and RPI returned comments into the final report. We thank everyone who has made it possible to create the conceptual design for the RPI 2020 linac and this report. Show Partial Abstract
