ITER provides Unique Technical Challenges for
Diagnostics
Measurement requirements demand performance
capability for present-day machines
alpha-particle measurement, operation in
radiation environment, presence of blankets,
reliability, calibration maintenance, control
data for machine protection. Significant
engineering design issues.
Port-plug with penetrations for Thomson
scattering, interferometry, etc.

Construction Schedule

• 7 year construction
• 1 year integrated commissioning
• ITER Legal Entity established about2 years
  before award of construction license
• Long lead item calls for tender sent out and
  procurement started before license awarded
• Success-oriented schedule First plasma in 2013
