Fractional electric quadrupole shifts for the E2 and E3 clock transitions corresponding to the different geometrical parameters: (a), (b) diameter 2ro of the inner electrode; (c), (d) tip-to-tip separation 2z0 of the inner electrodes; and (e), (f) angles θo at which the outer electrodes are machined. Each figure consists of a set of plots for angles of the inner electrode θi, which are 0° (black), 10° (red), 20° (gray), 30° (green), 40° (cyan), 50° (blue), and 60° (purple). The dashed line connects data points for the fixed values of θi and 2ro = 1 mm and 2z0 = 0.7 mm for all of them.
