Proyecto OPENDATA4ICTS

Referencia: RED2022-134332-I

Área: Ciencias Físicas

Subárea: Física de partículas y nuclear

Título: Datos en Abierto para Instalaciones Científico Técnicas Singulares Basadas en Aceleradores

Tipo: Redes ICTS


The optimal use of research infrastructures requires that the wider scientific community has adequate access to the data produced. This requires that data are produced and stored in a way that makes them easy to access. For that purpose, the FAIR principles (Findability, Accessibility, Interoperability, Reusability) have been stated and developed.

The accelerator-based ICTS, CNA and CMAM, which form the distributed network IABA, produce an important set of data in each accelerator experiment carried out. Typically, these experiments generate a set of counts in different detectors of a detector array, which should be complemented with data from the accelerator diagnostics.

Such wealth of data is often lost after each analysis, in such a way that users only refer to a count rate, where some background subtraction and fitting are performed. In many other cases, data are stored in specific formats that make any reuse initiative impractical. Proper storage of the raw data obtained from accelerator-based experiments, along with the relevant metadata, would be highly beneficial.

To address these challenges, the project has been structured into several objectives:

Objective 1: Define a Common Data Management Plan

The document “Data Management Policy IABA-ICTS” jointly developed for CNA and CMAM, has been drafted and reviewed by researchers. It outlines the guidelines for data collection, storage, and sharing within the IABA-ICTS network.

Objective 2: Define a Standard Format Containing the Relevant Metadata

This objective required collaboration with researchers to define all the necessary parameters to contextualize experiments. A distinction was made between two categories of metadata:

  • General metadata: Information that improves the discoverability, accessibility, and reuse of experimental datasets. Collected via: https://beamtime.cmam.uam.es/
  • Technical metadata: Essential for the correct interpretation and reusability of measurement data (beam characteristics, detector configurations, etc.).

Furthermore, both CNA and CMAM are actively contributing to the NAPMIX project (Nuclear, Astro, and Particle Metadata Integration for eXperiments). More information available at: NAPMIX Project Website

Objective 3: Develop Specific Software

We opted for a desktop application for each technique using React and Node.js. The applications can be accessed in the following GitHub repository (private access): GitHub Repository.

To request access, please contact: rvarela@us.es

Download Installers (.exe):

Note: Since this is an executable file (.exe), you may see warnings from Windows Defender. You can safely trust and install the application.

The application uses JSON format and connects to the internal MySQL database (allowed only for CNA/CMAM IPs) to retrieve metadata automatically.
