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.

Cross sections for the production of gamma rays by bombardment with 14.2-MeV neutrons were measured for 20 samples ranging from beryllium to plutonium. Differential cross sections are given as a function of gamma-ray energy over the region from 0.2 to 9.0 MeV for angles between the incident neutrons and emitted photons of 90 to 130 deg. For some of the light elements, cross sections are also presented for individual gamma rays. Pulsed-beam neutron time-of-flight techniques were employed to reduce background effects in the large NaI(Tl) gamma-ray spectrometer.
