“…In 1913, Geiger and Marsden upgraded the experiment and showed that the scattering follows Rutherford's equation [4]. Their design became the most common experimental setup used in advanced undergraduate [5] or scientific research [6] laboratories around the world. These types of apparatus are very expensive and require some radiation safety since they demand alpha radiation sources.…”

We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an electronic box. The chamber emulates the alpha particle source, the gold or aluminum foil, and the Geiger detector, which permits a real interaction by the students with the experiment simulating the real one. The electronic box has an Arduino board inside, which is responsible for simulating the particle count as a function of the scattering angle. The results obtained for gold and aluminium are similar to those found using a commercial apparatus. This low-cost didactic apparatus can be mimicked or improved from a source archive (both 3D model and Arduino project), which may help spread chemistry and physics concepts in a ludic but effective applied point of view.

The semiconductor detector of ionizing radiations is rapidly becoming standard equipment in nuclear physics research experiments. The devices have many advantages the most important of which is that they can be made into spectrometers. The elementary physics of their operation is outlined here together with the techniques of their use. Details are also given of some student laboratory experiments that have been performed with silicon detectors in order to demonstrate certain aspects of nuclear and solid-state physics.
