Description of the activity
Aim: To expand the area of measurements through the beam energy increas: Mean electric potential φ, mean plasma density ne, RMS of φ, RMS of ne in ECR heated plasmas, NBI heated plasmas and NBI+ECR heated plasmas.
Technique: scanning with probing beam with different energies (90-180 keV) in series of the reproducible TJ-II discharges.
Mandatory requirement: reproducibility of the plasma parameters during experimental day (<5%), density control (<5%), vacuum vessel wall conditioning, lithium coating before experimental day.
