Description

Overview: This repository contains data links for High-Dynamic-Range Mapping, including both raw and reduced 3D reciprocal space maps for 1T-TaSe2 from Quantum Materials (QM2) Beamline within the temperature range of 120 K to 300 K at various cooling rates. The experiments took place at the QM2 beamline of the Cornell High Energy Synchrotron Source (CHESS) in between 2025-1 cycle by Dr. Yu He’s group from Yale University. The corresponding CHESS beamline scientist overseeing the project is Suchismita Sarker.

Data Structure and Analysis: The data is organized with a prefix that identifies the principal investigator (PI), beamtime request ID, and beamline cycle: chen-4339-a. The JSON file includes several subdirectories for the data stored on the CHESS server: data_location_raw and data_location_reduced. The data_location_raw folder contains SPEC files and .cbf files. The data_location_reduced folder contains files with .nxs extensions, where data analysis has been performed using QM2 in-house code.

Detailed Data Analysis: The Data Analysis has been performed by NxRefine.
