Beam Tuning pictures:
Smallest beam spot at 0 Degree port
The beam appears to light up a 3 mm diameter circle on the Phosphorus screen.
Smallest beam spot at 90 Degree port
The beam appears to light up a [math]\displaystyle{ 8mm \times \frac{3.5 cm}{7.5cm} = 4 mm }[/math] diameter circle on the Phosphorus screen with [math]\displaystyle{ 20 \pm 10 \mu A }[/math] of beam current.
Max Transmission
Retune machine to maximize transmission between the FC collar and the FC.
