Precise Lifetime Measurement of the Cesium 5²D₅⸝₂ State

Experimental data from an atomic physics experiment measuring the lifetime of the cesium 52D5/2 state using atoms in a vapor cell. The dataset includes raw photon arrival time tags and pre-generated histograms from multiple measurement cycles, provided alongside Python scripts for evaluation. The data was collected by Sebastian Pucher at TU Wien and is associated with the paper arXiv:1912.10089.

Use Cases

• Validate fluorescence lifetime measurement algorithms based on raw photon time-tag data.
• Study the effect of temperature on atomic state lifetime based on data collected at temperatures from 23°C to 116°C.
• Benchmark single-photon counting module (SPCM) data analysis techniques using the provided reference and fluorescence photon datasets.

Strengths

• Data is directly linked to a published scientific paper (arXiv:1912.10089), providing clear academic context.
• Includes both raw time-tag data and pre-processed histograms with a 5 ns bin length for convenience.
• Covers multiple experimental conditions, including data used across several figures and at different vapor cell temperatures.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• For some measurements, reference SPCM time-tags are missing, as noted in the description.
