Energy confinement time

From FusionWiki
Jump to: navigation, search

The energy confinement time is defined as a function of the global plasma energy content, W, and the applied total heating power, P: [1]

$ \tau_E = \frac{W}{P-dW/dt} $

It is one of the main figures of merit of magnetically confined plasmas, and one of the factors of the Lawson criterion for fusion.
