Description

High-energy physics on collider exploits large-scale instruments and infrastructures which are inaccessible for educational purpose. Possibly individual detection elements can be used to discover a given technology, but such simple setups do not illustrate properly the concept of combining various measurements to characterize particles. This is especially true for tracking devices, which requires multi-layer instrument and magnetic field. However, the current technology trend tends to miniaturize sensors and allows the realization of complex systems at the tabletop scale.
The SiTrInEO project (Silicon Tracker for International Education Objective) intends to benefit from these advances in order to offer a small affordable setup allowing students to exercise all aspects of particle tracking. The initiative was started by two universities, KNU-Daegu and Unistra-Strasbourg, and joined by INFN-Frascati.
The instrument concept is based on two pairs of CMOS pixel sensors 1 placed around a small permanent magnetic, which can track and bent low energy electrons (MeV/c range) produced by a standard beta-emitter radioactive sources. The sensors are thinned to 50 µm in order to minimize the largest nuisance process, i.e. multiple scattering.
The development stage relied on existing material and expertise, but was largely conducted by students. The setup uses 3-D printed mechanical support allowing elements to be moved and an affordable DAQ system based on FPGA[2]. Two instruments are now operated quite routinely by students at KNU and Unistra in the context of their academic studies.
This talk will re-trace the simulation work which lead to the design of the instruments and review typical performances achieved. We will also discuss the type of activities conducted by students in the project.
