Description of the activity

Motivation and Background

Basic information to understand the relevance of the proposed experiments in the bigger context of fusion plasma research. You can use references, e.g, [1].

Proposal Objectives

Inject TESPELs containing compounds of interest (e.g. Li2CO3) and atomic elements (Al, Ti, Fe Cu, Ni, Mn, W) that are candidates for use in the OP2.1 campaign in W7-X. The principal aim is to identify strong emission lines from the atomic states of these elements in order to prepare filterscopes for the W7-X TESPEL system.

Approach and Methodology

Basic description of the experimental approach to meet the proposal objectives (e.g. parameter scans, configuration variation, operation schemes).


International or National funding project or entity

Include funding here (grants, national plans)

Description of required resources

Required resources:

  • Number of plasma discharges or days of operation:
  • Essential diagnostic systems (without which, the proposal cannot be conducted):
  • Other diagnostic system of special interest:
  • Type of plasmas (heating and magnetic configuration):
  • Specific requirements on wall conditioning if any:
  • External users: need a local computer account for data access: yes/no
  • Any external equipment to be integrated? Provide description and integration needs:

Preferred dates and degree of flexibility

Preferred dates: (format dd-mm-yyyy)

(If remote participation is required or preferred, please, indicate it here. A Zoom connection with the local contact person will be arranged on the day of experiments.)
