INL’s Teton supercomputer open for business
Idaho National Laboratory has brought its newest high‑performance supercomputer, named Teton, online and made it available to users through the Department of Energy’s Nuclear Science User Facilities program. The system, now the flagship machine in the lab’s Collaborative Computing Center, quadruples INL’s total computing capacity and enters service as the 85th fastest supercomputer in the world.

Magnetic activity of plasma during the injection of 2-8 MW non-relativistic electron beam of sub-millisecond duration in GOL-3 is studied.The main parameters of fluctuations of the magnetic field are discussed. In most experiments the m = 1 azimuthal mode has the largest value, although, higher modes stay significant. Amplitude of the largest perturbations is ~1/2 of the beam radius. The phase grows monotonically, rotational velocity agrees well with the expected E×B drift.Longitudinal velocity of the fluctuations was also measured, its value v ~ 107 cm/s is close to the ion sound speed for Te ~ 100 eV.
