Job Details

Job description:

The candidate will work on the EPSI project, Electron Positron Space Instrument, (CUP I53D23000640006) which aims to design, develop and optimize a future space experiment dedicated to the direct measurement of the flow of electrons and, separately, very high energy cosmic positrons. To this end, EPSI aims to develop a new technique for the discrimination of electrons and positrons starting from the detection of synchrotron radiation (X-rays) emitted when it passes through the Earth's magnetic field. In particular, the X-ray detector has to guarantee sufficient granularity to allow the detection of individual photons emitted along the curvilinear trajectory of electrons and positrons, while ensuring high detection efficiency for photons with energy between 1 and 100 keV.

The project consists of two work packages, which complement each other. The first is dedicated to hardware development. We will start with the characterization and implementation of the minimum detection unit. Upon completion, a small prototype of the flight detector will be built. The second work package will focus on the software part using Monte Carlo simulations. The work will focus on optimizing the geometry of the flight detector, with particular attention to energy resolution, angular resolution, and background rejection, as well as defining the optimal orbit. Based on their skills, the successful candidate will contribute one or more of the work packages described above.




The University of Florence is one of the most important Italian public universities and has a strong international vocation.

It fosters cooperation with academic and research institutions all over the world and welcomes foreign teaching staff, researchers and students to promote cultural and scientific internationalization. To this end, through its Departments and Schools, the University promotes the hospitality of highly qualified guests from all over the world.

Moreover, it traditionally devotes particular attention to the development of collaborative relationships with foreign universities and to the process of internationalization, which has become a strategic and dominant aspect of the life of the university in research, teaching, the organization of study programmes, mobility of teachers, researchers and students.

For these reasons, the University of Florence qualifies itself as one of the privileged destinations for international guests.
