“…The lost points moved opposite the helical coil side when we changed the magnetic field direction from counterclockwise to clockwise from the top view [101]. We chose four positions suitable for detecting charged fusion products using a virtual reality system [102,103]. The locations of the detectors (𝑥, 𝑦, 𝑧) were (2507 mm, 1900 mm, 1080 mm), (3145 mm, −64 mm, −1080 mm), (2405 mm, 1516 mm, 774 mm,), and (2837 mm, 187 mm, −774 mm).…”
