First Announcement:

The “Current State and Future of Neutron Stress Diffractometers” workshop will take place in Lucas Heights (Sydney’s suburban area where ANSTO is located) from Tuesday 10 January to Thursday 12 January 2012 at the AINSE Lecture Theater.

The ANSTO’s Bragg Institute (BI) and the Institute of Materials and Engineering (IME) invites you to attend a workshop which provides a forum for the instrument scientists of the neutron diffractometers and interested users to share their research results, to contemplate ways of instrument development and to discuss problems of instrumentation for the needs of the user community.

Purpose and motivation:

Neutron diffraction stress analysis in the last years has been featured by building versatile high-resolution TOF spectrometers based on high flux spallation sources: VULCAN (SNS), TAKUMI (J-PARC), ENGIN-X (ISIS). This also sets a very high standard for the major user research facilities based on neutron reactors in the matter of design and capabilities of the stress diffractometers (scanners) utilizing the constant wavelength neutron diffraction. In order to improve their efficiency and competitiveness few apparent ways have been explored involving more efficient use of the neutrons by utilizing focusing monochromators, neutron beam guides, multi detector systems, radial collimators, all in different combinations. The matter of optimal configuration of these elements is still a topic of debate. Contributions from the instrument scientists from the major reactor facilities (TUM, ILL, NCNR, BI, JRR-3) are intended to present state-of-art of the neutron stress diffractometers STRESS-SPEC (TUM), SALSA (ILL), BT8 (NIST) , RESA (JAEA), KOWARI (ANSTO) and facilitate further discussion.

The aims and focuses of this workshop are:

to review and access recent important technical developments in the area of neutron scanners/diffractometers based on steady-state reactors, especially techniques related to the radial collimators, neutron focusing devices (monochromators, neutron guides, lenses, etc.), positioning systems.
to present experimental scientific and technical results obtained recently in leading neutron reactor facilities using advanced neutron optical devices.
to bring forward new methodical developments for the purpose of optimal use of the neutron instruments.
to identify new (alternative) technical development paths and ideas toward competitiveness of the neutron diffractometers in the area of stress scanning and in-situ studies using neutron diffractometers.
to get input from the user community, to identify their current/future experimental needs and discuss the scientific program with new Kowari diffractometer in a broad context.

Due to the limited number of participants the programme will be held in one session, & we will not be holding a poster session. At the end of workshop a narrower board of participants will be invited to write a workshop report with recommendations for further development of the OPAL neutron stress diffractometer Kowari.
