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.

International or National funding project or entity

Include funding here (grants, national plans)

Description of required resources

  • Number of plasma discharges or days of operation:
  • Essential diagnostic systems:
  • Type of plasmas (heating configuration):
  • Specific requirements on wall conditioning if any:
  • External users: need a local computer account for data access: yes/no
  • Any external equipment to be integrated? Provide description and integration needs:
