Partikellinien
Partikellinien is a term used in some Finnish-language physics literature to describe a class of linear features observed in data from particle and plasma diagnostics. The concept covers both spectral and imaging contexts, where narrow, elongated signals indicate organized emissions, absorptions, or particle trajectories. In spectroscopy, partikellinien refer to distinct lines produced by transitions of particles or ions, while in detector imaging they describe straight or near-straight tracks associated with charged particles.
Origin and usage vary by subfield. The term appears in Nordic and European conference proceedings and journal
Characteristics commonly associated with partikellinien include morphology, origin, and diagnostic value. Lines may be Doppler-broadened or
Applications span plasma spectroscopy, fusion research, astrophysical spectroscopy, and detector calibration. By analyzing partikellinien, researchers infer
