Overview
A new initiative for Grazing Incidence standardisation was started with a survey at SXNS17. The first online meeting of the "Grazing Ray Initiative" was held on October 21st 2024.
The working group was formed at canSAS-VIII in Japan. At canSAS-XI in Freising it was agreed that we would liaise with the reflectometry community, who are having a meeting in October 2019. Tim Snow is organising that meeting and Adrian Rennie and Andrew Jackson are likely to be attending. Sebastian Jaksch is interested in doing some work on GISANS standards.

GISANS Data Reduction and Analysis Upgrades Initiative:
An initiative on “GISANS data reduction and analysis upgrades” was launched at the GISAXS-25 meeting in Hamburg in November 2025. The objective of the initiative is to develop a generic, instrument-independent software framework for GISANS data reduction and analysis that can be used across neutron research facilities.
Approach:
The proposal is to build upon the open-source software package BornAgain and to identify and define the key developments required for broader GISANS usability. Planned areas of improvement include:
- more flexible treatment of instrument resolution,
- improved background subtraction,
- clearer approaches to normalization,
- increased interoperability with existing analysis and reduction software tools.
Planned Work:
A dedicated working group has to be established with two primary tasks:
1. Defining a roadmap and priority list for the required functionality.
2. Implementing these features in collaboration with the BornAgain core development team. Contributions may include code development, example scripts, and other shared resources.
Next Steps:
The GISANS community is being invited to participate in the initiative. A first workshop is planned for the first half of 2026, with Institut Laue-Langevin (ILL) proposed as the host venue. The meeting is intended to be held on-site, with the option for remote attendance.
