TL;DR

This paper presents the Integrated Spectral Analysis Workbench (ISAW), a coordinated, interactive visualization system for neutron scattering data that enables real-time synchronization across multiple viewers—such as 2D images, 3D instrument displays, and spectral graphs—allowing users to explore complex datasets through linked, dynamic views. The key contribution is a unified, extensible framework where user interactions in one viewer (e.g., hovering over a data point) are instantly reflected in all connected viewers, significantly improving data interpretation efficiency for large, multi-detector datasets from neutron scattering experiments.

ABSTRACT

The overall design of the Integrated Spectral Analysis Workbench (ISAW), being developed at Argonne, provides for an extensible, highly interactive, collaborating set of viewers for neutron scattering data. Large arbitrary collections of spectra from multiple detectors can be viewed as an image, a scrolled list of individual graphs, or using a 3D representation of the instrument showing the detector positions. Data from an area detector can be displayed using a contour or intensity map as well as an interactive table. Selected spectra can be displayed in tables or on a conventional graph. A unique characteristic of these viewers is their interactivity and coordination. The position "pointed at" by the user in one viewer is sent to other viewers of the same DataSet so they can track the position and display relevant information. Specialized viewers for single crystal neutron diffractometers are being developed. A "proof-of-concept" viewer that directly displays the 3D reciprocal lattice from a complete series of runs on a single crystal diffractometer has been implemented.

Motivation & Objective

• To address the challenge of visualizing and analyzing large, complex neutron scattering datasets from multi-detector experiments.
• To improve data interpretation by enabling real-time, coordinated interaction across multiple visualization views.
• To develop an extensible, interactive framework that supports diverse data types, including 2D images, 3D instrument models, and spectral graphs.
• To support specialized analysis for single crystal neutron diffractometers through proof-of-concept viewers for reciprocal space visualization.

Proposed method

• The system employs a coordinated viewer architecture where user interactions (e.g., mouse hover or selection) in one viewer are propagated to all linked viewers of the same dataset.
• Multiple visualization types are supported: 2D intensity maps, 3D instrument geometry displays, scrolled lists of spectra, and interactive tables for area detector data.
• A 3D reciprocal lattice viewer was implemented as a proof-of-concept for single crystal diffractometer data, directly displaying the full reciprocal space from a series of experimental runs.
• The framework is built to be extensible, allowing integration of new viewers and data types as needed for different experimental setups.
• Inter-viewer coordination is achieved through a shared data model and event-driven communication between viewers.
• The system supports both real-time interaction and data exploration across large datasets from multiple detectors.
