[Neutron] 2006 Clifford G. Shull Prize Recipient: Dr. J. M. Carpenter, I

The Neutron Scattering Society of America (NSSA) established the Clifford G. Shull Prize in Neutron Science to recognize outstanding research in neutron science and leadership promoting the North American neutron scattering community. The prize is named in honor of Prof. Clifford G. Shull, who received the Nobel Prize in 1994 with Prof. Bertram Brockhouse for seminal developments in the field of neutron science. The establishment of the prize was announced at the inaugural American Conference on Neutron Scattering (ACNS) in 2002.

The nominations were reviewed by a committee of experts in the field of neutron science and the NSSA is pleased to announce that the 2006 recipient of the Shull Prize is Dr. J. M. Carpenter, Intense Pulsed Neutron Source Division of the Argonne National Laboratory. The prize and $5000 honorarium will be awarded at the 2006 ACNS, St. Charles, IL, June 18-22, 2006 (http://acns2006.anl.gov/).

Dr. Jack Carpenter has been a pivotal figure in the development of the next generation of neutron sources world-wide. Jack’s work pioneered exploitation of the inherent efficiency of the spallation process for the production of neutrons together with the advantages of pulsed operation and time-of-flight measurements for the study of structure and dynamics of materials. His patented design for the moderator-reflector combination is at the heart of modern neutron source design and his creativity in matching the characteristics of neutron sources to the demands of the instrumentation and ultimately the scientific drivers continue to serve as an example to the international community. Jack's demonstrations of the advantages of the spallation process for neutron production led to the development of the Intense Pulsed Neutron Source at Argonne and KEK in Japan, the success of which paved the way for facilities such as ISIS in the United Kingdom and the Lujan Center at Los Alamos. The success of these facilities led to proposals for more advanced pulsed source facilities such as the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory, AUSTRON in Austria, J-PARC (a KEK and JAERI collaboration) in Japan and the ESS project in Europe.
With a design power of 1.4MW and an upgrade path to more than 2 MW, the SNS is DOE’s flagship facility for neutron research and it will become the leading neutron facility worldwide when fully instrumented. It is fair to say that the US would not now be devoting $1.4B to the construction of the SNS were it not for the groundbreaking work by Dr. Carpenter over a long productive career. In addition to his contributions to source technology, Jack has made seminal contributions to the development of pulsed source instrumentation such as focusing algorithms for time-of-flight powder and single crystal diffractometers and the design of converging multi-aperture collimator for SANS. Indeed Jack's emphasis on the coupled optimization of neutron source performance characteristics and instrument design has greatly increased our ability to exploit pulsed neutron sources as tools for a broad range of scientific endeavor. Jack's advice on technical and strategic issues is widely sought and his input into the design of the SNS, as well as new sources in Japan and Europe, has been invaluable.
In summary, his pioneering development of modern spallation neutron sources, their targets, the decoupled moderator reflector concept, cryogenic moderators, and time-of-flight instruments in general establish Jack Carpenter as a pivotal figure for the present and future of neutron scattering in North America and throughout the world.
