R&D for R3B Si tracker

Lead Research Organisation: University of York
Department Name: Physics


This project supports preparatory work for a state-of-the-art detector array that will give a better insight into the structure of the atomic nucleus. The device will be employed at the FAIR facility in Germany, which provides the highest energy beams of exotic nuclei. Exotic nuclei are short-lived nuclear species that are crucial for our understanding of the cosmos. These beams of exotic species impinge on a reaction target of pure liquid hydrogen and, following a violent reaction, several fragments of subatomic scale emerge in all directions; this device helps to track the emitted charged particles and from this information reconstruct the quantum state and structure of the exotic nucleus.

Description in this project we completed the performance evaluation of an existing instrument and explored the possible future technologies for constructing an array for precise tracking of light charged particles in nuclear physics experiments.
Exploitation Route The outcomes concern mostly the nuclear and particle physics community. Regarding the evaluated device, the electronics of the bespoke ASIC electronics of the instrument are better understood and the performance of the device has been evaluated. Regarding the future technologies for a charged particle array, the work has investigated (through simulations) the performance of pixel-based monolithic Silicon detectors and prepared the ground for a larger project grant application. The relevant technology, besides fundamental nuclear and particle research, it can also serve medical imaging, nuclear security and space applications.
