WEST claims latest plasma confinement record
The French magnetic confinement fusion tokamak known as WEST maintained a plasma in February for more than 22 minutes—1,337 seconds, to be precise—and “smashed” the previous record plasma duration for a tokamak with a 25 percent improvement, according to the CEA, which operates the machine. The previous 1,006-second record was set by China’s EAST just a few weeks prior. Records are made to be broken, but this rapid progress illustrates a collective, global increase in plasma confinement expertise, aided by tungsten in key components.

We describe a new formulation of the Monte Carlo approach to particle transport problems by defining a direct point flux estimator that extracts information from “passage” points rather than “collision” points. The approach leads directly to the radically new concept of track rotation and provides a statistical framework in which it is possible to prove the validity of the track rotation concept in spherically symmetric configurations and the validity of the compensated track rotation concept in nonspherically symmetric configurations. The approach can lead to essentially infinite gains in efficiency over conventional analog Monte Carlo methods that cannot directly estimate the flux at a point.
