This paper describes an analysis dataset from the Large Helical Device (LHD) documenting the particle fraction (E, E/2, E/3) of positive-ion-based beam injectors for NBI#4A, including averaged time traces and related fraction and power terms across 13107 time points. The “population” here is not human subjects but experimental plasma beam-injection parameters, with data stored as a compressed analysis file tied to shot number 133404 (sub-shot 1). The key outputs are the defined variables (e.g., avg_fraction_1st/2nd/3rd_nb4a and fraction_* and fraction_*_#4ua/#4la) rather than an interpretive biological or mechanistic conclusion, and the explicit limitation is that the record is a dataset description without broader contextual results. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
