On this page you will find the spot size measurments performed on 23 november 2021 by Emily, Marjolein and Casimir. Spotsizes were measured by tracing the beam shape on white paper in a cardboard holder placed inside the beam. Three different tracings were measured at each distance to get a more accurate measurement.

Measurement table

The distance in the table is measured to the inside of the vacuum chamber. To get the distance to the slit, 94 mm needs to be added to the distance in the table.
