a Argon signal in detection zone II as function of the horizontal (blue squares) or vertical (red triangles) position of the valve. Error bars represent standard errors of the means. b Scan of the vertical position of the laser focus when the valve is positioned close to the center (corresponding to arrow “A” in panel a) or 4 mm below the center (corresponding to arrow “B” in panel a). The grey lines in (a) and (b) show simulations with different values of the effective size of the beam source
