GEMS, as the leader of the consortium composed of itself, C3D, Optimal Optik and AEMI has recently signed a Framework Contract with ITER IO. This 4+2 years Framework Contract targets the delivery of the mechanical design, analysis and prototyping of all components of the Erosion Deposition Monitor: the work affects the full system, from the in-vessel optics enclosure, which will be installed under the ITER Divertor dome, to the back end data collection system installed in the diagnostic hall. The goal of the Framework Contract is to progress the Erosion Deposition Monitor (EDM) design from its current state (post Conceptual Design Review, CDR);

  1. to the Preliminary Design Review, PDR, of the full system
  2. to the Final Design Review FDR, of the in-vessel and Port Cell (ISS and PCSS) components,
  3. deliver a set of prototype in-vessel components
  4. and deliver final manufactured in-vessel components ready for installation on ITER.

Top section of the optical box under the divertor dome – a key component of the whole system. It will be fully exposed to harsh envirionment of the divertor casettes.
The first Task Order implementing the tasks of the Framework Contract was launched.
[12 September 2021] It will last until November 2022 and will target the progress of the EDM design from its current state (post Conceptual Design Review, CDR) to the Preliminary Design Review, PDR state, the completion of the PDR and resolution of the Category 1 chits (most severe issues raised during the design review) if any.

Major references

GEMS Engineering is deeply involved in and fully devoted to the success of the ITER project. As a result, our main reference works are in connection with ITER, and - more closely - to its diagnostic systems.

The ITER device, currently under construction in the south of France, will study the potential of controlled nuclear fusion to provide energy for mankind. In order to study the behaviour of this device, a set of monitoring systems (referred to as Diagnostics) is required. These Diagnostics will provide the information required to understand the performance of the device.
