Plasma Physics (Physics/ECE/NE 922) Seminar
Towards steady-state fusion reactor with Wendelstein 7-X
Time: 12:05 pm
Place: 2241 chamberlin hall
Speaker: Marcin Jakubowski, IPP Greifswald
Abstract: Wendelstein 7-X, large superconducting stellarator, went into operation in 2015. With a 30 cubic meter volume, a superconducting coil system and steady state heating capabilities of up to 10 MW, it is built to demonstrate the benefits of optimized stellarators approaching those of a fusion power plant. One of the main aims of W7-X is to show that stellarators can operate with reactor relevant, steady state power and particles exhaust concept. Most recently, it operated with inertially cooled divertor and achieved very encouraging results. The heat deposition follows the strike line patterns expected from edge modelling with broad deposition profiles. Moreover, thanks to boronization, high plasma densities were achieved. This lead to remarkable results of complete divertor detachment across all 10 divertors. We see a reduction of peak power being reduced by a factor of 5 or larger and significantly enhanced neutral compression in the divertor volume. At the same time no degradation of core confinement was seen.

NPAC (Nuclear/Particle/Astro/Cosmo) Forum
The Final Word from MINOS+ on Neutrino Oscillations
Time: 2:30 pm
Place: 4274 Chamberlin Hall
Speaker: Tom Carroll, University of Texas at Austin
Abstract: MINOS+ is a long-baseline neutrino oscillation experiment with two functionally identical magnetized detectors located in Fermilab's NuMI beamline. Together, MINOS+ and its predecessor, MINOS, have collected 13 years of neutrino data from the NuMI beam as well as the atmosphere. The combined MINOS and MINOS+ dataset measures muon neutrino oscillations in the 3-flavor paradigm unlike any other experiment.
