Measurements of vertical distances between wire and cathode and of horizontal distances between wires 03/28/2003
As made for other prototype we measured the distances of wires of the short prototype.
In following plots we report the performed measurements.
The errors on the measurement of the height to focus the wire is about 0.005 mm.
The errors on the measurement of the height to focus the grafite is about 0.005 mm.
Than the errors on the distance between wire and grafite is 0.01 mm.
In following plot we used an overestimated errors for the distances of 0.05 mm.
Short prototype
It seems not so bad, considering the fact that the heights of wires have been regulated by hands.
