This dataset describes the particle fraction measurements (E, E/2, E/3) of positive-ion-based beam injectors, specifically ion source NBI#4A, on the Large Helical Device (LHD). Data are organized as time-series analysis results (DimNo=1, 13107 time points) for averaged fractions from the 1st, 2nd, and 3rd components, along with related fraction measures for two power channels (#4ua and #4la), using shot number 83521 and sub-shot 1. The key “finding” is the provision of these computed fraction variables via an analysis file ([email protected]) rather than a reported experimental conclusion. The paper itself does not state any study limitation, but the content is a data description tied to specific LHD operating conditions. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
