Title: Status of the Spallation Neutron Source

Speaker: Phil Ferguson (Oak Ridge National Lab，USA)

Host: Dr. CHEN Hesheng, IHEP Director

Time: 15:00, Sept.28 (Wednesday), 2011

Place: Room C305, IHEP Main Building

Abstract: Since completion of the construction project in April 2006, attention has focused on improving the performance and reliability of the Spallation Neutron Source, commissioning neutron scattering instruments, and obtaining early science results. This talk will focus on the design goals and current operating conditions at the SNS. Current target system development activities, including target and advanced moderator development, as well as Post Irradiation Examination of the first three SNS target vessels, will be covered. Finally, plans for the SNS, including the Power Upgrade Project (PUP) and the Second Target Station (STS) will be discussed.

About the speaker: Phillip D. Ferguson has been the leader of the Neutron Source Development Group at SNS, Oak Ridge National Lab since 2006. The neutron source development group is responsible for neutronics, the development of mercury target, cryogenic moderator and reflector, and the post irradiation examination of material at SNS. He is also thechairman of SNS Radiation Safety Committee, and working for planning the SNS second target station. He started working on SNS target station design in 2000 and was theneutronics team leader since 2004 for the physics design and moderator commission of the SNS target station, the shielding design of SNS facility, and development of particle transport programs for accelerator applications.

Phillip received his Ph.D in Nuclear Engineering from University of MO-Rolla. He worked for radiation damage, Neutronics analysis and design of target station at Los Alamos National Laboratory during 1989-2000. He is author of more than 100 scientific publications in peer review journals and international conferences. He was also the chair of Accelerator Applications Division of American Nuclear Society 2009-2010.
