On this page you will find the spot size measurements performed by Vikas and Casimir early July. These measurements were used to determine the beam size inside the sample chamber. Details about the opening of the slits have not been recorded. But since non of the members did not touch the dials, it was assumed by Casimir the entrance slit was opened 1.65 (mm) and the exit slit 3.05 (mm). At these distances the shape of the spot was assumed to be round. Therefore the spot size is given in one measurement, the diameter.
