Balanced double-null configurations are of general interest for boundary plasma physics. and they have been proposed for some future designs. Experimental observations demonstrate absence of plasma fluctuations in tokamak high-field side scrape-off layer in a balanced double-null configuration (Smick et al. 2013). https://www.roneverhart.com/10mm-Male-GRAV-Angled-Quartz-Banger-45/
