Stern-Gerlach results

The first results for the Stern-Gerlach experiment are in. Our data production has been rushed through, and the results have been analysed. The data transmission from the experimental area to the main site (my office) was found to be rather slow. The exact rate was 0.144 MB per minute, but could be doubled if I didn't stop for a coffee on the way over with my floppy disk.

Anyway, here are the results: The black points show the profile of an atomic beam as the detector is slowly moved across the beam. I pushed the detector by hand, so you can't really compare the positions of the maxima for the four measurements. The width of the beam is a couple of millimetres. When the inhomogeneous magnetic field is turned on by passing a current through the electromagnet the beam is split into two. You would expect that the two beams have the same intensity, but one is always larger than the other: maybe something is cutting the beam off for positions in the left of the plot. The next step will be to reattach a motor which moves the detector automatically, and to check the alignment of all the components.
