Charge collection distance measurements for a diamond detector using a strontium-90 source

This dataset contains charge-collection-distance (CCD) measurement data for a planar polycrystalline CVD diamond detector measured with a strontium-90 beta source. The purpose of the dataset is to document the experimental CCD response of the detector and to support the analysis presented in the associated manuscript, “Charge-carrier transport simulations in diamond detectors with electric-field-dependent mobility and charge-collection-distance-based trapping”. The data are organized by bias polarity (positive, negative), detector state (pumped, unpumped), and applied bias voltage (100 V to 500 V). The dataset includes voltage-resolved measurement files together with the Python analysis script used to process the data, extract charge spectra and most probable values, and derive CCD and CCE summary quantities. These files support reproducibility of the reported measurements and their interpretation in the context of charge transport and trapping in diamond detectors.
