Course: 2022/2023

Plasma-wall interactions in fusion plasmas

(18822)

Master in Mathematical Engineering (Plan: 460 - Estudio: 88)

EPI

Coordinating teacher: MARTIN SOLIS, JOSE RAMON

Department assigned to the subject: Physics Department

Type: Electives

ECTS Credits: 3.0 ECTS

Course: 2º

Semester: 1º

Requirements (Subjects that are assumed to be known)

Basic knowledge of atomic and surface physics (graduate level)

Objectives

The course intends to provide with a basic understanding of the physical and chemical processes responsible for material erosion and plasma contamination during the interaction of fusion plasmas with plasma facing materials. The concepts of edge transport, divertor configuations, neutral particle behaviour and impurity screening will be addressed. Challenges in material selection and present developments in the field will be extensively reviewed. The course will provide the student with an appropiate training in plasma-material interactions, of interest not only in fusion plasmas but also in plasma technology and material processing.

Learning activities and methodology

* Teaching Methods : Classroom lectures and classroom problem solving sessions. Homework assignments * Course Material: Lecture notes. Virtual facilities (links to relevant web pages) will be also provided with the aim of improving the interaction with the lecturers and the learning of the subject

Assessment System

Evaluation shall take into account attendance and class participation, including practical classes and the solution of questionnaries periodically proposed by the lecturers along the course (30% of the final mark). A written-closed book exam will take place at the end of the semester (70% of the final mark).

% end-of-term-examination 70
% of continuous assessment (assigments, laboratory, practicals...) 30
