11th

Canadian Neutron Scattering Summer School

11

Scattering Summer School was held from May 9 to 13, 2011 at Chalk River Laboratories (CRL). The school was jointly funded by Canadian Institute for Neutron Scattering (ClNS), Atomic Energy of Canada Limited

(ABCL), and National Research

Council (NRC) Canadian Neutron Beam Centre (CNBC). The school attracted 39 enthusiastic participants, mostly graduate students, from across Canada, US and Europe. This year's school followed the Chall<: River tradi-tion by providing an overview of the theory and applications of neutron scat-tering in various fields rather than focusing on a narrow theme during morning lectures followed by afternoon hands-on experiments.

Initial lectures concentrated on the basic and general concepts in neutron scattering and later ones became more focused. John Root (CNBC) began the lectures on Monday with an overview of neutron sources, indicating that despite several new builds, the demand for neu-trons is surpassing the supply. This is certainly the case in Canada highlight-ing the urgent need of a new neutron source. Next, Tom Holden (Northern Stress Technologies) eloquently pre-sented the basic properties of neutron. Finally, powder neutron diffraction technique was presented by Ian Swains on (CNBC).

On Tuesday, Carl Adams (St. . Francis Xavier University) presented

the basic ｴｨｾｯｲｹ＠ of inelastic neutron

scattering. Zin Tun (CNBC) gave a very stimulating lecture on the theory and instrumentation of neutron reflecto-metry drawing from comparisons with

optics, and Michael Gharghouri

(CNBC) presented texture, stress, and strain measurements.

The Wednesday lectures were .,on more focused topics, the first being on small angle neutron scattering 'by

Neutron News

Norbert Kucerka (CNBC). Chris

Wiebe (University of Winnipeg and University of Manitoba) gave an

excel-lent ｰｲ･ｳ･ｾｴ｡ｴｩｯｮ＠ of the basic theory of

magnetic tfeutron scattering, highlight-ing the unique capabilities of magnetic neutron scattering through several

examples. Maikel Rheinstadter

(McMaster University and CNBC) gave the final lecture on triple axis spectroscopy.

On Thursday, Dominic Ryan

(McGill University, Canada) presented polarized neutron scattering and Lee

Robertson (Oak Ridge National

Laboratory) provided an excellent over-view of neutron scattering instrumenta-tion in both reactor and spallainstrumenta-tion sources. Bill Buyers (CNBC) presented quantum materials applications, using results on high temperature cuprate superconductors as an example, he demonstrated that neutrons can reveal the space and time scales of materials.

The lectures culminated on Friday by presentations on applications of neu-tron scattering in a variety of fields:

in situ neutron reflectometry in corro-sion studies by Jamie Noel (University of Western Ontario), industrial applica-tions by Ron Rogge (CNBC), and bio-logical applications by John Katsaras (Oak Ridge National Laboratory).

The demonstrations held at NRU reactor, included powder diffraction, triple axis spectroscopy, polarized neu-tron reflectometry, stress and strain measurements and small angle neutron diffraction. The experiments comple-mented the lectures providing students an opportunity to gain experience in setting up instruments, and collecting and analyzing data. The time spent with staff at NRU also gave students ample opportunity to discuss in more details any questions they had.

A Public Lecture Series formed part of the school. Bob Walker, the new Senior Vice President of Nuclear

Zin Tun (CNBC) explains the measurement of nano-structures at surfaces made at the D3 neutron refiectometer. (photo credit: National Research Council Canada).

Laboratories presented science policy concerning nuclear power. As 2011 marks the 1 st centennial of the

discov-ery

of

Tremblay (University of Sherbrooke) commemorated this special occasion. Jeremy Whitlock (ABCL) gave the final lecture on 'the history of CRL and many "firsts" for Canada in nuclear science and technology.

The school's traditional barbecue was held on Thursday with volleyball and a campfire. Fortunately due to hold-ing the school earlier this year, fewer bottles of bug repellent were needed!

Students and lecturers alike provided positive feedback. Many students appre-eiated the broad introduction to various techniques. The school's success could be summarized by this student response: "I gained a lot from this summer school and will strongly recommend to others to initiate collaborative research work to make use of this technique."

We warmly thank: all of the speal<:ers and ClNS, ABCL, NRC, and CNBC staff

in mal<:ing the 11th Canadian Neutron

Scattering Summer School a success!
