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/Western-Digital-Ultrastar-DC-HC570-WUH722222ALE6L1-22TB-7-2K-RPM-SATA-6Gb-s-512e-SED-3-5in-Recertified-Hard-Drive/
