This item is a data set describing the particle fraction of positive-ion-based beam injectors (ion sources) for the LHD negative-ion-based NBI#4A, reported at energy settings E, E/2, and E/3. It provides averaged fractions over 13107 time points for shot 74272 (sub-shot 1), including values for different beam components and related power-fraction and per-stage fraction metrics. A key caveat is that the provided content is purely observational/data-description metadata rather than a study with results, analysis, or explicitly stated limitations. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Read from the paper's body, not the abstract. Not a substitute for reading the paper. No clinical advice. How this works
