Gomtraic
A remote school of
tokamak
operation
Duration-3 months, a few remote experimental sessions during this period
Open for all students around the worldTasks: breakdown studies, plasma position studies, electron temperature estimate, first wall conditioning…No participation feeWebpage: https://sites.google.com/site/gomtraic/homeSlide24
Sumtraic
An experimental training course in Prague (usually in August/September)
2 weeks of experimental activity on COMPASS/Golem
Tasks: magnetic measurements, probe diagnostics, microwave measurement, optical diagnostics
