Description of the activity, including motivation/objectives and experience of the proponent (typically one-two pages)

A triple bundle recently acquired will be used to simultaneously measure three atomic line intensities in Helium plasmas. The goal is to obtain simultaneously the plasma edge electron temperature and density and compare them with other diagnostics as done in the past with a double bundle [1] . Further, the camera exposure time will be reduced to the minimum acceptable value taking into account the Signal to Noise Ratio in order to see if turbulence-relevant times can be achieved (of the order of a few tens of microseconds). If this is possible, the electron density and temperature of Blobs will be measured and see if the plasma turbulence is coupled to the neutral density as proposed in the past [2].


If applicable, International or National funding project or entity

ENE2015-68206-P

Description of required resources

Required resources:

  • Number of plasma discharges or days of operation: 1
  • Essential diagnostic systems: Thomson Scattering, microwave interferometer,
  • Type of plasmas (heating configuration): Helium Plasmas with Limiter C inside the LCFS, ECRH and NBI, Standard 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:

Preferred dates and degree of flexibility

Preferred dates: June 2018
