Task Title: INTERN-SCOP07-Multi-machine analysis of wall conditioning in fusion devices & its application
Domain: Science & Operation
 
Department: Science,Controls & Operation
Division: Science
 
Section: Experiments and Plasma Operation 
Duration (in months): 6 months
Location: 
France, 13067 St Paul Lez Durance Cedex      
Description of tasks: 

Fusion devices are high vacuum systems which require efficient conditioning to provide a good vacuum and low background of impurities before efficient plasma operations are possible. Different techniques are used such as baking and ion-induced conditioning techniques but each device has its own recipe which is a consequence of the different plasma-facing materials and conditioning/heating capabilities. This internship aims at identifying common denominators amongst those different recipes to allow extrapolations to ITER.

 

Task 1: Review conditioning techniques performed in existing (and past) fusion devices and gather experimental data (Residual Gas Analyses) during baking and conditioning
Task 2: Perform a kinetic analysis of the evolution of the partial pressures of various impurities from analysis of existing data and knowing the pumping capacities, PFC mix, baking temperature and leak rate of the different devices. Extrapolate to ITER for the capabilities available before First Plasma and assess the required baking duration
Task 3: Perform a similar exercise for the cleaning efficiency of ion-induced conditioning techniques (such as ICWC, GDC, etc.) to assess the required GDC duration in ITER
 


 

 

The ITER Organization offers internship opportunities to undergraduate and postgraduate students with the objective of providing these students with the opportunity to gain practical experience in their field of study, whilst collaborating in an international, scientific and multicultural environment.  Internships are offered for up to six months, extendable for up to one year (depending on the category).  To find out more about our internship program, please refer to our website (click here)


For any further questions, please contact internships@iter.org

 

Internship opportunities are limited to nationals from countries participating in the ITER Project (China, the European Union plus Switzerland, India, Japan, Korea, Russian Federation, and the United States).

 
Please also note that interns are not considered staff members and shall, therefore, not have the status of "Staff" as per the ITER Agreement and the Headquarters Agreement (see more information on these constitutive agreements in Legal Resources).  Neither the ITER Staff Regulations nor the privileges and immunities granted to ITER Organization staff are applicable to interns.  The ITER Organization salary, pension scheme, and social insurance coverage do also not apply.
