2D electron density profile evolution during detachment in Super-X divertor L-mode discharges on MAST-U

Autor: Lonigro, N., Doyle, R. S., Verhaegh, K., Lipschultz, B., Moulton, D., Ryan, P., Allcock, J. S., Bowman, C., Harrison, J., Silburn, S., Theiler, C., Wijkamp, T. A., Team, the WPTE, Team, MAST-U

2D electron density profiles obtained from coherence imaging spectroscopy in different MAST-U divertor conditions are compared. The data includes variations of strike point position, core electron density, and heating power. The improved performance

Report

First demonstration of Super-X divertor exhaust control for transient heat load management in compact fusion reactors

Autor: Kool, B., Verhaegh, K., Derks, G. L., Wijkamp, T. A., Lonigro, N., Doyle, R., McArdle, G., Vincent, C., Lovell, J., Federici, F., Henderson, S. S., Osawa, R. T., Brida, D., Reimerdes, H., van Berkel, M., team, The EUROfusion tokamak exploitation, team, the MAST-U

Nuclear fusion could offer clean, abundant energy. However, managing the immense power exhausted from the core fusion plasma towards the divertor remains a major challenge. This is compounded in emerging compact reactor designs which promise more cos

Report

First 2D electron density measurements using Coherence Imaging Spectroscopy in the MAST-U Super-X divertor

Autor: Lonigro, N., Doyle, R., Allcock, J. S., Lipschultz, B., Verhaegh, K., Bowman, C., Brida, D., Harrison, J., Myatra, O., Silburn, S., Theiler, C., Wijkamp, T. A., Team, MAST-U, Team, the EUROfusion Tokamak Exploitation

2D profiles of electron density and neutral temperature are inferred from multi-delay Coherence Imaging Spectroscopy data of divertor plasmas using a non-linear inversion technique. The inference is based on imaging the spectral line-broadening of Ba

Report

Divertor shaping with neutral baffling as a solution to the tokamak power exhaust challenge

Exhausting power from the hot fusion core to the plasma-facing components is one of the biggest challenges in fusion energy. The MAST Upgrade tokamak uniquely integrates strong containment of neutrals within the exhaust area (divertor) with extreme d

Investigations of atomic \& molecular processes of NBI-heated discharges in the MAST Upgrade Super-X divertor with implications for reactors

This experimental study presents an in-depth investigation of the performance of the MAST-U Super-X divertor during NBI-heated operation (up to 2.5 MW) focussing on volumetric ion sources and sinks as well as power losses during detachment. The parti

Operative First Web Contracture Management: Current Strategies

Autor: Doyle R. Wallace, MD, Waldo E. Floyd, III, MD, FAOA

Publikováno v: JBJS Open Access, Vol 9, Iss 4 (2024)

Abstract. » First web contractures can be due to nonthermal trauma, burns, congenital differences, and Dupuytren contracture. » Mild cases are managed with contracture release and full-thickness skin graft or when surrounding skin is pliable, Z-pla
