## TL;DR

PRISM is a MATLAB application that streamlines the management and visualization of probe data in tokamak diagnostics, improving accuracy and efficiency over manual methods.

## Contribution

It introduces a flexible, GUI-based tool for structured probe registration, metadata management, and 2D/3D visualization in tokamak experiments.

## Key findings

- Enhanced accuracy in probe data documentation
- Improved visualization of probe setups
- Potential for integration with digital twins

## Abstract

The successful operation of tokamak experiments requires accurate documentation, tracking, and visualization of diagnostic instruments, particularly electrical probes. Traditionally, this metadata is maintained manually through handwritten logbooks or semi-digital spreadsheets, leading to inefficiencies and human errors. In response to these challenges, we present PRISM (Probe Registration and Information System for Monitoring)-a MATLAB-based application developed using App Designer. PRISM provides a graphical user interface (GUI) that facilitates structured probe registration, metadata storage, and both 2D and 3D spatial visualization in tokamak geometries. Tested with data from the ADITYA-U tokamak, PRISM helps users enter information accurately, retrieve metadata easily, and visualize probe setups. The tool is built in a flexible way, is not limited to a specific setup, and could potentially support future developments such as digital twins and real-time control systems.
