The course ran from Monday (May 23, 2016) to Wednesday (May 25, 2016). All presentations were given in English. Registration began at 8:15 on Monday, in the DLR School Lab (Building 6).
The course was divided in half day lectures and practices. Each course day included a one hour lunch break and coffee breaks. The lectures on Thursday covered a demonstration experiment. A detailed time table can be downloaded here.
