Tungsten and Copper Photocathode Characterization Images

Raw .tif files from experiments characterizing W(111) and Cu(001) photocathodes, used to determine spectral Mean Transverse Energy (MTE) and Quantum Efficiency (QE). The dataset was authored by Ir-Jene Shan and last updated on April 20, 2026. It contains data for W(111) from July 16, 2024, and for Cu(001) from February 26-27, 2025.

Use Cases

• Calculate spectral Mean Transverse Energy (MTE) based on the experimental .tif files mentioned in the description
• Determine Quantum Efficiency (QE) characteristics for tungsten and copper photocathodes based on the described raw data
• Compare the performance of W(111) and Cu(001) photocathode materials using the provided experimental image files

Strengths

• Data size is 212.1 MB, indicating a medium-scale collection of image files.
• Provides experimental data for two distinct photocathode materials (W(111) and Cu(001)).
• Includes temporal metadata for the experiments (July 2024 and February 2025).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
