Researchers at the Centre for Energy Research, Hungary, will test key elements of the ITER disruption mitigation system in a dedicated support laboratory.

The technology group, led by Uron Kruezi, of the ITER Disruption Mitigation Task Force has awarded a multi-year contract to the Centre for Energy Research (EK), together with several Hungarian companies, for the development of a laboratory to test key components of ITER's disruption mitigation system (DMS). The DMS will use a technique called shattered pellet injection that creates small ice fragments by shattering a single large cryogenic pellet of hydrogen and neon. These fragments will then enter the plasma to protect the in-vessel components from the large heat fluxes generated during disruptions. One of the lab's first tasks will be to study the pellet fragmentation process, and to design a pellet shattering unit that produces those fragment sizes that are most effective in mitigating disruptions.

The studies carried out under this contract are part of a wider technology program that ITER carries out with its partners. This program addresses for example the optimization of the pellet formation process, the development of an optical pellet diagnostic to measure pellet velocity and integrity, as well as technology development for accelerating the pellet towards the plasma.

The ITER Organization has kicked off its 2021 internship program with the publication of 116 offers on the ITER website (visit Jobs/Internships here: https://www.iter.org/jobs/internships).

These opportunities are geared toward undergraduate and postgraduate students, with a broad array of topics across scientific, technical and support departments. Control and data acquisition, systems engineering, business operations, construction and installation, safety and security, and science and technology are all represented in this year's batch of internship opportunities.

Positions are offered for up to six months; some categories are extendable to one year. Apply before 28 February 2021 through the online e-recruiting system. (Please note that internship opportunities are limited to nationals from countries participating in the ITER Project, i.e., China, the European Union plus Switzerland, India, Japan, Korea, Russian Federation and the United States.)
