Electric field profiles comparing the TPX capillary (A–D) with the DoubleDee (E–H) in a 1 mm I.D. 2-loop–1-gap LGR. A) Eϕ and B) Eρ along a 0.25 mm radius circle concentric with the sample loop, showing an electric field peak at the LGR gap at 0°. C) Eϕ along the line parallel to the gap (solid) and perpendicular to the gap (dashed), D) Eρ perpendicular to the gap. E) Eϕ showing discontinuities of the electric field at the DoubleDee septum and F) Eρ showing tangential electric field null. Plots are for septum orientations perpendicular (solid) and parallel (dashed) to the electric field along a 0.5 mm concentric circle. G) Eϕ perpendicular to the gap for the septum orientation parallel to the gap (solid) and Eϕ parallel to the gap for the septum orientation perpendicular to the gap (dashed). H) Eρ perpendicular to the gap for the septum orientation parallel to the gap.
