Active projects

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.

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

Alignment jigs for mounting the outer vessel steady state sensors of the ITER fusion reactor

Induction heating of the bolt samples. A total of 15000 thermal cycles were performed between 100 and 200 °C
GEMS Engineering Ltd. has become the first ever Hungarian private company, that has supplied components to be used for the assembly of the ITER fusion reactor.
The ITER machine will be used for scientific-technological purposes, to help the engineers and scientists know how the fusion plasma behaves at large scales. For this reason, one of the most important components of this huge machine are the small magnetic diagnostic sensors which will need to be perfectly mounted to have accurate signals from them before, during, and after the plasma pulses. GEMS Engineering Ltd. won the contract for the design and manufacturing of jigs for the alignment of the tangential and normal outer vessel steady state magnetic sensors in three sectors (2, 5 and 8). GEMS produced 10 pieces of jigs which would be used to accurately set-up all the 60 sensors. These jigs will “only” be used for aligning the sensors and they will be removed thereafter, in order not to contaminate the components that remain attached to the vacuum vessel. During the manufacturing, exclusively certified stainless steel and bronze raw materials were allowed to be used.

Project completed!
[11 January 2022] The jigs were shipped to the ITER Organization to Cadarache, France in mid-January 2022 and they will be used for mounting of the sensors from April onwards.

Infrastructure development for ITER’s in-vessel diagnostic signal transmission

Divertor/In-vessel loom clamp
Divertor/In-vessel loom clamp
GEMS Engineering have concluded a number of contracts with ITER IO with the aim to contribute to the development of the in-vessel electrical infrastructure that is responsible for signal transmission of numerous plasma diagnostic systems. Items to develop include cable trays, cable looms, clamps, clips, connectors, etc. Activities delivered to ITER include design, finite element analysis, prototype and mock-up manufacturing and testing development of special tooling, etc.

Examples of some manufactured prototypes and mockups are below. GEMS engineers and manufacturing experts have gained, among others, plenty of valuable expertise during the manufacturing of these items in terms of manufacturing optimization (speed, optimum raw material usage, cost, and alike).

We have also tested these components for functionality, installability, assemblability, etc.

Front end optics enclosure with Vertical Targets (IVT left, OVT right)
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.
