Evidence on the effects of main-chamber neutrals on density shoulder broadening

Basil Duval, Nicola Vianello, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Cedric Kar-Wai Tsui, Mirko Wensing, Marcelo Baquero Ruiz, Artur Perek, Sophie Danielle Angelica Gorno

Evidence that density shoulder broadening is dependent on high main-chamber neutral density is presented. Shoulder broadening does notoccur when the sources for main-chamber neutrals are minimized using divertor baffles and wide gaps to the first wall (sim ...
