Presented by Alpha & Supak Adviser: Julien Hillairet Yellow Fusion Team Electron Temperature & Plasma Life Time
Objectives Plasma Life Time How long that we can extract the energy? Electron Temperature How much energy that we can obtain?
Group Hypothesis Current Drive Voltage related to Plasma current Fusion Power -> Kinetic energy -> Density of particle Density -> Presurre
